Finite Difference Methods for Option Pricing under Lévy Processes: Wiener-Hopf Factorization Approach [PDF]

open access: yesThe Scientific World Journal, 2013
In the paper, we consider the problem of pricing options in wide classes of Lévy processes. We propose a general approach to the numerical methods based on a finite difference approximation for the generalized Black-Scholes equation.

Weyl metrics and Wiener-Hopf factorization [PDF]

open access: yesJournal of High Energy Physics, 2020
We consider the Riemann-Hilbert factorization approach to the construction of Weyl metrics in four space-time dimensions. We present, for the first time, a rigorous proof of the remarkable fact that the canonical Wiener-Hopf factorization of a matrix ...

Diffraction by a Semi-Infinite Parallel-Plate Waveguide with Five-Layer Material Loading: The Case of H-Polarization

open access: yesApplied Sciences, 2023
In this paper, the plane wave diffraction from a semi-infinite parallel-plate waveguide with five-layer material loading is rigorously analyzed for H-polarization using the Wiener–Hopf technique. The Fourier transform of the scattered field is introduced

Gärtner–Ellis condition for squared asymptotically stationary Gaussian processes

open access: yesModern Stochastics: Theory and Applications, 2015
We establish the Gärtner–Ellis condition for the square of an asymptotically stationary Gaussian process. The same limit holds for the conditional distribution given any fixed initial point, which entails weak multiplicative ergodicity.

Calculation of Probability of the Exit of a Stochastic Process from a Band by Monte-Carlo Method: A Wiener-Hopf Factorization

open access: yesMathematics, 2019
This paper considers a method of the calculation of probability of the exit from a band of the solution of a stochastic differential equation. The method is based on the approximation of the solution of the considered equation by a process which is ...

Wiener--Hopf operators admit triangular factorization [PDF]

open access: yesJournal of Operator Theory, 2019
We prove that every positive bounded invertible Wiener--Hopf operator admits triangular factorization. This answers the question posed by L. Sakhnovich in 1994.

Matrix Wiener–Hopf–Hilbert Factorisation [PDF]

open access: yesSIAM Journal on Applied Mathematics, 1986
Let A(\(\lambda)\) be a \(2\times 2\)-matrix function that is analytic and nonsingular on the cut complex plane \(G={\mathbb{C}}\setminus \{\pm (k+\delta)|\delta\geq 0\}\), where Re k, Im k\(>0\), such that \(\pm k\) are only branch points singularities. A matrix Wiener-Hopf factorization \(A(\lambda)=U(\lambda)L(\lambda)^{-1}\), U (resp.

On the solution of the convolution equation with a sum-difference kernel

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
The paper deals with the integral equations of the second kind with a sumdifference kernel. These equations describe a series of physical processes in a medium with a reflective boundary.

Two coupled Lévy queues with independent input

open access: yesStochastic Systems, 2014
We consider a pair of coupled queues driven by independent spectrally-positive Lévy processes. With respect to the bi-variate workload process this framework includes both the coupled processor model and the two-server fluid network with independent ...
