Bott‐integrable Reeb flows on 3‐manifolds
Journal of the London Mathematical Society, Volume 109, Issue 1, January 2024.Abstract This paper is devoted to studying a notion of Bott integrability for Reeb flows on contact 3‐manifolds. We show, in analogy with work of Fomenko–Zieschang on Hamiltonian flows in dimension 4, that Bott‐integrable Reeb flows exist precisely on graph manifolds.

The extended hypergeometric class of L\'evy processes
, 2014 With a view to computing fluctuation identities related to stable processes, we review and extend the class of hypergeometric L\'evy processes explored in Kuznetsov and Pardo (arXiv:1012.0817).

The Solvability and Explicit Solutions of Singular Integral–Differential Equations with Reflection
Abstract and Applied Analysis, Volume 2024, Issue 1, 2024.This article deals with a classes of singular integral–differential equations with convolution kernel and reflection. By means of the theory of boundary value problems of analytic functions and the theory of Fourier analysis, such equations can be transformed into Riemann boundary value problems (i.e., Riemann–Hilbert problems) with nodes and ...

Truncated Wiener–Hopf equation and matrix function factorization
Sibirskie Elektronnye Matematicheskie Izvestiya, 2020 The author considers the following convolution equation of second kind \[u(t)-\int_0^\tau k(t-s)u(s)\,ds=f(t)\] on the interval \((0,\tau)\), \(\tau>0\), where \(k\in L_1(-\tau,\tau)\) and \(f\in L_1(0,\tau)\). A~connection of this equation and the Riemann-Hilbert boundary value problem in the Wiener algebra whose matrix coefficient, denoted by \(G_ ...

On the solvability of boundary value problem for mixed-type equation with a singular coefficient
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 In this paper we study a problem with conditions on the inner characteristic and on some parts of the degeneration line for mixed type equation with singular coefficient in unbounded domain.

Numerical solution of scattering problems using a Riemann--Hilbert formulation [PDF]
, 2019 A fast and accurate numerical method for the solution of scalar and matrix Wiener--Hopf problems is presented. The Wiener--Hopf problems are formulated as Riemann--Hilbert problems on the real line, and a numerical approach developed for these problems ...

A note on Wiener-Hopf factorization for Markov Additive processes
, 2011 We prove the Wiener-Hopf factorization for Markov Additive processes. We derive also Spitzer-Rogozin theorem for this class of processes which serves for obtaining Kendall's formula and Fristedt representation of the cumulant matrix of the ladder epoch ...

Characterization of a Resistive Half Plane over a Resistive Sheet
, 1993 The diffraction of a resistive half plane over a planar resistive sheet under plane wave illum1ination is determined via the dual integral equation method (a variation of the Wiener-Hopf method).

F-electron spectral function of the Falicov-Kimball model and the Wiener-Hopf sum equation approach
Condensed Matter Physics, 2008 We derive an alternative representation for the f-electron spectral function of the Falicov-Kimball model from the original one proposed by Brandt and Urbanek.

A trifurcated waveguide problem II [PDF]
, 1994 We consider the diffraction of the dominant plane wave mode which propagates out of the end of a semi-infinite waveguide. This waveguide is made up of a half plane with a Dirichlet boundary condition and a half plane with a Neumann boundary condition ...
