摘要

The aim of the paper is to study problem of financial derivativespricing based on the idea of the Heston model introduced in [9]. Followingthe approach stated in [6] and in [7] we construct the regularised version ofthe Heston model and the discrete duality finite volume (DDFV) scheme forthis model. The numerical analysis is performed for this scheme and stabilityestimates on the discrete solution and the discrete gradient are obtained. Inaddition the convergence of the DDFV scheme to the weak solution of theregularised Heston model is proven. The numerical experiments are providedin the end of the paper to test the regularisation parameter impact.
