Alternatives to the Black-Scholes-Vasicek deflator introduced in [25] are proposed. They are based on the multivariate Wang variance-gamma process considered in [66]. As an application, closed form analytical multiple integral formulas for pricing the European geometric basket option with a deflated multivariate exponential Wang variance-gamma asset pricing model are derived. Mathematics Subjec...

Abstract. Markov Random Fields are widely used in many image processing applications. Recently the shortcomings of some of the simpler forms of these models have become apparent, and models based on larger neighbourhoods have been developed. When single-site updating methods are used with these models, a large number of iterations are required for convergence. The Swendsen-Wang algorithm and Pa...
