In this paper,the option pricing problem is formulated as a distributionally robust optimization problem,which seeks to minimize the worst case replication erro
In this paper,we study the Holder regularity of weak solutions to the Dirichlet problem associated with the regional fractional Laplacian(-△)Ωα on a bounded
Multigrid methods are widely used and well studied for linear solvers and precondi-tioners of Krylov subspace methods.The multigrid method is one of the most po
In this paper,a toxin producing phytoplankton-zooplankton model with inhibitory substrate and time delay is investigated.A discrete time delay is induced to bot
