A formula for the derivatives of holomorphic functions in C2 in terms of certain integrals taken on boundaries of analytic varieties

open access: closedJournal of Mathematical Analysis and Applications, 2003
The setting for the author's integral representations is the following: \(D\)~is a bounded domain in~\(\mathbb C^2\) with smooth boundary; the variety~\(V\) is the zero set of a function holomorphic in a neighborhood of the closure of~\(D\), and \(V\) is assumed to meet the boundary of \(D\) transversely in a smooth curve; \(M\)~is the intersection \(V\

On properties of h-differentiable functions

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2021
Research in the theory of functions of an h-complex variable is of interest in connection with existing applications in non-Euclidean geometry, theoretical mechanics, etc.

Aspects of univalence in holographic axion models

open access: yesJournal of High Energy Physics, 2022
Univalent functions are complex, analytic (holomorphic) and injective functions that have been widely discussed in complex analysis. It was recently proposed that the stringent constraints that univalence imposes on the growth of functions combined with ...

On some extension of Paley Wiener theorem

open access: yesConcrete Operators, 2020
Paley Wiener theorem characterizes the class of functions which are Fourier transforms of ℂ∞ functions of compact support on ℝn by relating decay properties of those functions or distributions at infinity with analyticity of their Fourier transform.

An analog of the Cauchy formula for certain Beltrami equations

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
The Beltrami differential equations are intrinsic generalizations of the Cauchy–Riemann system in complex analysis. Their solutions generalize holomorphic functions. As known, solutions to many problems of the complex analysis are based on application of

Dimer models and conformal structures

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

Equivariant toric geometry and Euler–Maclaurin formulae

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.
