Minimal surfaces with symmetries
Proceedings of the London Mathematical Society, Volume 128, Issue 3, March 2024.Abstract Let G$G$ be a finite group acting on a connected open Riemann surface X$X$ by holomorphic automorphisms and acting on a Euclidean space Rn$\mathbb {R}^n$ (n⩾3)$(n\geqslant 3)$ by orthogonal transformations. We identify a necessary and sufficient condition for the existence of a G$G$‐equivariant conformal minimal immersion F:X→Rn$F:X\rightarrow

A nonlocal problem for fourth order hyperbolic equations with multiple characteristic
Electronic Journal of Differential Equations, 2002 In this paper, we study fourth order differential equations with multiple characteristics and dominated low terms. We prove the existence and uniqueness of a Riemann function for this equation, and then provide an integral representation of the general ...

Word maps with constants on symmetric groups
Mathematische Nachrichten, Volume 297, Issue 1, Page 165-173, January 2024.Abstract We study word maps with constants on symmetric groups. Even though there are non‐trivial mixed identities of bounded length that are valid for all symmetric groups, we show that no such identities can hold in the limit in a metric sense. Moreover, we prove that word maps with constants and non‐trivial content, that are short enough, have an ...

Solvability of the Goursat problem in quadratures
, 2020 We find new variants of Goursat problem solution in quadratures on the basis of the combination of the Riemann method and the cascade integration. The results are applied to two Volterra equations with particular integrals.

Goursat problem for two-dimensional second-order hyperbolic operator-differential equations with variable domains [PDF]
, 2012 We develop a modification of the energy inequality method and use it to prove the well-posedness of the Goursat problem for linear second-order hyperbolic differential equations with operator coefficients whose domains depend on the two-dimensional ...

The global solution of a Goursat problem for the polyvibrating equation of order 2p
, 1985 The paper deals with a Goursat problem for the polyvibrating equation of order 2p. The question is reduced to a system of integro-functional Volterra equations and then the existence of the unique global solution of above-said problem is proved.Michalski
