Monotonicity theorem for subharmonic functions on manifolds [PDF]
, 2022 We provide a sharp monotonicity theorem about the distribution of subharmonic functions on manifolds, which can be regarded as a new, measure theoretic form of the uncertainty principle.

On the differential equations of frozen Calogero-Moser-Sutherland particle models
, 2023 Multivariate Bessel and Jacobi processes describe Calogero-Moser-Sutherland particle models. They depend on a parameter $k$ and are related to time-dependent classical random matrix models like Dysom Brownian motions, where $k$ has the interpretation of ...

On four-dimensional Goursat problem in the non-classical treatment for a hyperbolic equation [PDF]
arXiv, 2013 There is substantiated the four-dimensional Goursat problem with non-classical conditions for a hyperbolic equation.

, 2020 An open-source package for symbolic analysis of second-order ordinary differential equations with polynomial coefficients is proposed. The approach is mainly based on the singularity structure of the equation and the routines are written under the open ...

A potential system with infinitely many critical periods
, 2023 In this paper, we propose an analytical non-polynomial potential system which has infinitely many critical periodic orbits in phase plane. By showing the existence of infinitely many $2\pi-$ periodic solutions, the proof bases on variational methods and ...

Notes on commutative algebra and harmonic analysis [PDF]
arXiv, 2004 Fourier series with absolutely summable coefficients provide a classical example of a commutative Banach algebra, and these notes are concerned with this and related matters.

A Note on the Convolution of Circle Impulses [PDF]
arXiv, 2021 We present a formula for the convolution $\delta_{C_1}*\delta_{C_2}$ of two circle impulses. The derivation uses a classical addition theorem for Bessel functions.
arxiv
, 2011 We show that the coefficients of the three-term recurrence relation for orthogonal polynomials with respect to a semi-classical extension of the Laguerre weight satisfy the fourth Painlev\'e equation when viewed as functions of one of the parameters in ...
