We evaluate the two-photon exchange correction to the unpolarized cross
section in the elastic muon-proton scattering within dispersion relations. One
of the six independent invariant amplitudes requires a subtraction. We fix the
subtractio...

We explore the application of probability generating functions (PGFs) to
invasive processes, focusing on infectious disease introduced into large
populations. Our goal is to acquaint the reader with applications of PGFs,
moreso than to deri...
A generalization of Croot-Lev-Pach's Lemma and a new upper bound for the
size of difference sets in polynomial rings

Croot, Lev and Pach used a new polynomial technique to give a new exponential
upper bound for the size of three-term progression-free subsets in the groups
(Z4​)n.
The main tool in proving their striking result is a simple lem...

We consider the bounded linear operators with domain in the Hilbert space
L2(Sn), n=2,3,5 and describe its symbolic calculus defined by the Berezin
quantization. In particular, we derive an explicit formula for the composition
of Bere...

In two previous papers we showed that any analytically integrable vector
field admits a local analytic Poincar\'e-Birkhoff normalization in the
neighborhood of a singular point. The aim of this paper is to extend this
analytic normalization...
Certificates in P and Subquadratic-Time Computation of Radius, Diameter,

In the context of fine-grained complexity, we investigate the notion of
certificate enabling faster polynomial-time algorithms. We specifically target
radius (minimum eccentricity), diameter (maximum eccentricity), and
all-eccentricity comp...

The enumeration of shortest paths in cubic grid is presented herein, which
could have importance in image processing and also in the network sciences. The
cubic grid considers three neighborhoods - namely, 6-, 18- and 26-neighborhood

We discuss some new aspects of the theory of the Jimbo-Miwa-Ueno tau function
which have come to light within the recent developments in the global
asymptotic analysis of the tau functions related to the Painlev\'e equations.

The Navier-Stokes transport coefficients for a model of a confined
quasi-two-dimensional granular gas of smooth inelastic hard spheres are derived
from the Enskog kinetic equation. A normal solution to this kinetic equation is
obtained via ...

In this paper, we study the inner product of states corresponding to weights
of finite-dimensional highest-weight representations of classical groups.
We prove that the action of the raising operators would reduce a state of
