Kolmogorov-Smirnov test of the scaling function
Under the significant level of 5%, the null hypothesis is rejected for six stocks (000625, 600026, 600100, 600428, 600601, 600688) using the KS test and for five stocks (000625, 600026, 600100, 600428, 600601) using the KSW test. We find that the KS test and the KSW test provide very similar results except that the KS ...

Memory effect of return intervals
The probability distribution may not fully characterize the properties of volatility return intervals. The temporal correlation is known as another important observable independent of the probability distribution. Empirical studies have revealed that the stock market volatilities are long-term correlated. We suppose th...

Short-term memory of return intervals
To investigate the memory effect of the return intervals in Chinese stock market, we first calculate the conditional probability distribution P_q(\tau |\tau _0), which is the probability to find an interval \tau immediately after the interval \tau _0. Specifically, we study the conditional PDF for a bin of \tau _0. The...

Variational description of classical point-particle relativistic dynamics
In classical mechanics the variational functional (the Hamilton action functional) is well-known, and can be realized either by means of asynchronous or synchronous variational principles. The variational functional (action functional) is defined in terms of the curves r^{\mu }(s) and u_{\mu }(s), functions of the pr...

THM.2 implies the fundamental consequence that for point-particles the variational principle (REF ) becomes invalid if the EM 4-potential A_{\mu }^{(self)} is properly taken into account. This is due to the divergences produced by the self-force generated by the point particle. To deal with this basic difficulty severa...

Abstract
Some ingredients of the BRST construction for quantum Lie algebras are applied to a wider class of quadratic algebras of constraints. We build the BRST charge for a quantum Lie algebra with three generators and ghost-anti-ghosts commuting with constraints. We consider a one-parametric family of quadratic algebras with ...

Introduction
The construction of BRST charges Q for linear (Lie) algebras of constraints is well known. In the case of nonlinear algebras, despite the existence of quite general results concerning the structure of the BRST charges (see, e.g., , , and references therein), the general construction is far from being fully understood. ...

Double BRST complex
For an algebra, having several quadratic faces, related by nonlinear transformations, one can impose standard initial condition in any of them and build – in general nonequivalent – BRST charges (cf. the Lie algebra [x,y]=y and transformations x\mapsto x+f(y), f is a polynomial).

Conclusion
We extended some elements of the construction of BRST charge for quantum Lie algebras to more general quadratic algebras. We explicitly found the BRST charges in the examples when the constraints commute with the ghost-anti-ghosts. We discussed an example of a QLA with three generators and presented the BRST charge for...

Abstract
Recently a simple proof of the generalizations of Hawking's black hole topology theorem and its application to topological black holes for higher dimensional ($n\geq 4$) spacetimes was given \cite{rnew}. By applying the associated new line of argument it is proven here that strictly stable untrapped surfaces do possess...

Introduction
Hawking's black hole topology theorem plays a key role in 4-dimensional black hole physics from the beginning of the 70's. By making use of a variant of Hawking's argument, almost three decades later, in the late 90's, Gibbons and Woolgar could also characterize the so-called “topological black hole” spacetimes—to whic...

Finally, recall that {S} was assumed to be a strictly stable untrapped surface which ensures that the null normals n^a and \ell ^a may be assumed, without loss of generality, to be such that \left(£_n\theta ^{(\ell )}+\theta ^{(\ell )} \theta ^{(n)}\right) \vert _{{S}}\ge 0, and also that £_n\theta ^{(\ell )}+\theta ^{...

Abstract
We discuss the open charm production in peripheral reactions $\bar pp\to \bar Y_cY_c$ and $\bar pp\to M_c\bar M_c$, where $Y_c$ and $M_c$ stand for $\Lambda_c^+,\Sigma_c^+$ and $D,D^*$, respectively, at $\sqrt{s}\lesssim 15$ GeV, which corresponds to the energy range of FAIR. Our consideration is based on the topolo...

Introduction
Open charm production will be one of the major topics of the hadron and heavy-ion programme at FAIR . On the one hand, charm spectroscopy will be addressed by the PANDA collaboration , while the CBM collaboration will exploit charmed particles as probes of the nuclear medium at maximum compression. For both large-scal...

One can see an increase of the asymmetry with -t and its almost constant value at large \sqrt{s} and fixed t_{\rm max}-t. The difference in {\cal A} for \bar{K}^0K^{*0} and K^+K^{*-} final states is mainly due to the difference in tensor couplings in {K^*N\Sigma } and {K^*N\Lambda } interactions.

The ratio of the cross sections with D^-D^+ and \bar{D}^0D^0 final states is close to (\sqrt{2}\,g_{KN\Sigma }/g_{KN\Lambda })^4\simeq 0.034. The cross sections decrease rapidly with energy as s^{-6.18}, therefore, the region with small excess energy is more suitable for studying these reactions.

Reaction
In this section, we discuss the production of \bar{M}M (with \bar{M}M being \bar{K}K or D\bar{D}) in \bar{p}p collisions. We assume that at small momentum transfer -t, where t=(p_p-p_K)^2 or t=(p_p-p_{\bar{D}})^2, the dominant contribution comes from the baryon exchange channels.As an example, in Fig. REF (a) and (b) w...

Longitudinal asymmetry
In reactions \bar{p}p\rightarrow \bar{K}K (D\bar{D}) at forward production angle (or t=t_{\rm max}), the spin in the final state is equal to zero. This means that the production amplitude may be expressed asT_{m_i,n_i}\sim B(s)\,\delta _{m_i-n_i}~,and therefore, the asymmetry in Eq. (REF ) {\cal A}=1. At finite angles,...

Summary
In summary, we have analyzed the open charm production in the exclusive binary reactions \bar{p}p\rightarrow \bar{Y}_cY_c, \bar{p}p\rightarrow D\bar{D} and \bar{p}p\rightarrow D\bar{D}^* at small momentum transfer. Our consideration is based on a modified Regge type model, motivated by quark-gluon string dynamics. The ...

Abstract
Most real life systems have a random component: the multitude of endogenous and exogenous factors influencing them result in stochastic fluctuations of the parameters determining their dynamics. These empirical systems are in many cases subject to noise of multiplicative nature. The special properties of multiplicative...

This is again a nontrivial consequence of the multiplicative dynamics: in usual additive gain/loss games one ends up in a globally non-optimize Nash equilibrium. The attitude suggested by the analysis that follows is of ignoring events that never happen. It affects crucially the recommended level of sharing in very ris...

The Kelly terminology
As seen above, high risk, high gain potential processes generate a paradox: the naive expected wealth grows asymptotically to infinity while the probability for non-vanishing wealth (the survival probability) decreases exponentially. To overcome this puzzle, J. Kelly, initiated an approach that led to a vast literature...

The Kelly terminology
For N of order 10 (and p=0.55,d=1), the region of ”dangerous“ f's shrinks from 0.8 (out of 1) to 10^{-20} !! (Figure REF ,inset C). This fact allows the player not only to win more asymptotically, but also to shrink significantly the risk one takes! These results are presented in Figure  REF . [Figure: The curves in th...

Effects of asynchronous updating: infinite survival time for games with total loss
When the system has some kind of external clock one may treat it in a synchronous fashion: i.e. all agents update their endowments in the same instance. In many other systems the individuals are not updated simultaneously but rather asynchronously. The theoretical framework presented so far applies well to asynchronous...

Fixed group size and varied generosity.
Let us now fix the group size N and look at the asymptotic growth rate. In particular, we look at the case in which after each timestep one is donating to the other members of the group a fraction 0 \ge D \ge 1 of the difference between one's wealth and the average wealth of the group. In this way the accumulated wealt...

Altruism elicits in humans very powerful and diverse feelings. Its paradoxical nature makes it mysterious and challenging to understand. In fact, often one looks for hidden ulterior motives that would offer alternative explanations for an ostensibly altruistic behavior. Indeed, it is difficult to understand why a ratio...

Introduction
The theory of (semi-)Riemannian submersions, as a “dual” of that of Riemannian immersions, is a relatively new and vast subject of study, which since its introduction made by O'Neill in , and indipendently by Gray in , has been continously developing, due to its growing importance in the physical framework which try to...

Then, if x\in M, choosing an h\in H such that x\in U_{h}, and putting \sigma _{x}=\mathrm {Span}_{\mathbb {R}}((J_{1}^{h})_{x},(J_{2}^{h})_{x},(J_{3}^{h})_{x}), we get a three dimensional vector subspace \sigma _x of End(T_{x}M), which does not depend on the open set U_{h} and on the structure (J_a^{h})_{a=1,2,3}, such...

Preliminaries
If we suppose that, for each x\in M, the tangent space T_{x}M is a non degenerate subspace of (T_{x}\bar{M},\bar{g}_{x}), then necessarily the index of g_{x}:=\bar{g}_{x}| _{T_{x}M\times T_{x}M} does not depend on the point x. Therefore, with the only request that each T_{x}M is a non degenerate subspace of T_{x}\bar{M...
