Webb8 nov. 2024 · In this article, we consider the stochastic Cahn--Hilliard equation driven by additive noise. We discretize the equation by exploiting the spectral Galerkin method in space and a temporal accelerated implicit Euler method. Based on optimal regularity estimates of both exact and numerical solutions, we prove that the proposed numerical … Webb25 aug. 2024 · By establishing the convergence rate for the eigenvalues and the eigenfunctions, we obtain sharp convergence rates for the transition density and the price of options with nonsmooth payoffs. In particular, we show that for call-/put-type payoffs, convergence is second order, while for digital-type payoffs, convergence is generally …

The first accommodates continuous velocity and pressure interpolations; the second accommodates continuous velocities and discontinuous pressure. The natural “stability norm” provides control for the velocity in both cases. photo printing 7x5 https://mtwarningview.com
