Motivated by the pricing of first touch digital options in exponential Lévy models and corresponding credit risk applications, we study numerical methods for solving related partial integro-differential equations. The goal of the paper is to consider advantages of the Laplace transform-based...

We describe a numerical method for solving 3-dimensional partial differential equations, which arise in mathematical finance and other applications. The goal of the paper is to introduce a technique based on Wiener-Hopf factorization with application of Laplace transform. We analyze the problem...

We derive a general formula for pricing options with barrier and/or lookback features, which covers several types of options studied in the literature and new types of options, and demonstrate that the pricing formula can be efficiently realized using the methodology developed in Kudryavtsev and...

The paper suggest a new approach to pricing barrier options under pure non-Gaussian Levy processes with jumps of finite variation. The key idea behind the method to represent the process under consideration as a difference between subordinators (increasing Levy processes). Such splitting rule...
