报告摘要：In this talk,we present a numerical method and its fast implementation for the solution of awide class of semilinear parabolic equations including the Allen-Cahn equationas a special case. The method combines efficient decompositions of spatialdifference operators on a regular mesh with stable and accurate exponentialtime integrators. It can deal with stiff nonlinearity and both homogeneous andinhomogeneous boundary conditions of different types. Numerical experimentsdemonstrate effectiveness of the new approach for both linear and nonlinearmodel problems.
