Abstract
In the present chapter we consider two abstract Cauchy problems
and the boundary-value problem
for differential equations in an arbitrary Banach space E with the positive operator A and an arbitrary E parameter multiplying the derivative term. The high order of accuracy single-step uniform difference schemes generated by an exact difference scheme of the approximate solutions for differential equations of parabolic type with an arbitrary parameter e on the highest derivative are presented. The high order of accuracy two-step uniform difference schemes generated by an exact difference scheme of the approximate solutions for differential equations of the elliptic and hyperbolic types with an arbitrary parameter E on the highest derivative are presented. The well-posedness of these difference schemes for parabolic and elliptic equations in various Banach spaces is established. The stability estimates of solutions of a high order of accuracy difference schemes for hyperbolic equations with an arbitrary e parameter on the highest derivative are obtained.
