Discrete Methods for Parabolic Equations with Time-Dependent Coefficients

摘要: Publisher Summary This chapter describes some recent results concerning fully discrete methods of higher order in time for second-order parabolic initial-boundary value problems where the equations have time-dependent or nonlinear coefficients. The explains certain that are efficient sense amount work required problem is proportional to time-independent case. also discusses spatial discretization. further presents discretization based on a rational approximation an exponential function and how total problems.
