On multioperators principle for constructing arbitrary-order difference schemes

Abstract An arbitrary-order discretization technique based on linear combinations of non-centered compact operators (“multioperators”) for convection-diffusion type equations (in particular, fluid dynamics equations) is presented. Existence, positivity or negativity of multioperators essential for constructing stable schemes are investigated. Numerical examples are presented.
