Sharpened Strichartz estimates and bilinear restriction for the mass-critical quantum harmonic oscillator | We develop refined Strichartz estimates at $L^2$ regularity for a class of
time-dependent Schrödinger operators. Such refinements begin to
characterize the near-optimizers of the Strichartz estimate, and play a pivotal
part in the global theory of mass-critical NLS. On one hand, the harmonic
analysis is quite subtle ... | 0 | 0 | 1 | 0 | 0 | 0 |
A fast and stable test to check if a weakly diagonally dominant matrix is a nonsingular M-matrix | We present a test for determining if a substochastic matrix is convergent. By
establishing a duality between weakly chained diagonally dominant (w.c.d.d.)
L-matrices and convergent substochastic matrices, we show that this test can be
trivially extended to determine whether a weakly diagonally dominant (w.d.d.)

Task-Oriented Query Reformulation with Reinforcement Learning | Search engines play an important role in our everyday lives by assisting us
in finding the information we need. When we input a complex query, however,
results are often far from satisfactory. In this work, we introduce a query
reformulation system based on a neural network that rewrites a query to

Inverse scattering transform for the nonlocal reverse space-time Sine-Gordon, Sinh-Gordon and nonlinear Schrödinger equations with nonzero boundary conditions | The reverse space-time (RST) Sine-Gordon, Sinh-Gordon and nonlinear
Schrödinger equations were recently introduced and shown to be integrable
infinite-dimensional dynamical systems. The inverse scattering transform (IST)
for rapidly decaying data was also constructed. In this paper, IST for these

Relieving the frustration through Mn$^{3+}$ substitution in Holmium Gallium Garnet | We present a study on the impact of Mn$^{3+}$ substitution in the
geometrically frustrated Ising garnet Ho$_3$Ga$_5$O$_{12}$ using bulk magnetic

Inference on Auctions with Weak Assumptions on Information | Given a sample of bids from independent auctions, this paper examines the

robust way,... | 1 | 0 | 1 | 0 | 0 | 0 |

Image Registration for the Alignment of Digitized Historical Documents | In this work, we conducted a survey on different registration algorithms and

Inertia, positive definiteness and $\ell_p$ norm of GCD and LCM matrices and their unitary analogs | Let $S=\{x_1,x_2,\dots,x_n\}$ be a set of distinct positive integers, and let

Low-Latency Millimeter-Wave Communications: Traffic Dispersion or Network Densification? | This paper investigates two strategies to reduce the communication delay in

The structure of multiplicative tilings of the real line | Suppose $\Omega, A \subseteq \RR\setminus\Set{0}$ are two sets, both of mixed

The effect of temperature on generic stable periodic structures in the parameter space of dissipative relativistic standard map | In this work, we have characterized changes in the dynamics of a

The $u^n$-invariant and the Symbol Length of $H_2^n(F)$ | Given a field $F$ of $\operatorname{char}(F)=2$, we define $u^n(F)$ to be the
maximal dimension of an anisotropic form in $I_q^n F$. For $n=1$ it recaptures
the definition of $u(F)$. We study the relations between this value and the
