Slow plasma dynamo driven by electric current helicity in non-compact Riemann surfaces of negative curvature physics.plasm-ph Boozer addressed the role of magnetic helicity in dynamos [Phys Fluids \textbf{B},(1993)]. He pointed out that the magnetic helicity conservation implies that the dynamo action is more eas...

Gevrey regularizing effect of the Cauchy problem for non-cutoff homogeneous Kac's equation math.AP In this work, we consider a spatially homogeneous Kac's equation with a non cutoff cross section. We prove that the weak solution of the Cauchy problem is in the Gevrey class for positive time. This is a Gevrey regu...

On the renormalization of gauge theories in curved space-time hep-th We consider the renormalization of general gauge theories on curved space-time background, with the main assumption being the existence of a gauge-invariant and diffeomorphism invariant regularization. Using the Batalin-Vilkovisky (BV) formalism o...

Gain/loss asymmetry in time series of individual stock prices and its relationship to the leverage effect q-fin.ST Previous research has shown that for stock indices, the most likely time until a return of a particular size has been observed is longer for gains than for losses. We establish that this so-called ga...

On the Dark Matter Solutions to the Cosmic Ray Lepton Puzzle astro-ph.CO Recent measurements of cosmic ray leptons by PAMELA, ATIC, HESS and Fermi revealed interesting excesses. Many authors suggested particle Dark Matter (DM) annihilations could be at the origin of these effects. In this paper, we critically asses...

Monoidal 2-structure of Bimodule Categories math.QA math.CT We define a notion of tensor product of bimodule categories and prove that with this product the 2-category of C-bimodule categories for fixed tensor C is a monoidal 2-category in the sense of Kapranov and Voevodsky. We then provide a monoidal-structure pr...
