Approximations to the solution of Cauchy problem for a linear evolution equation via the space shift operator (second-order equation example)

Applied Mathematics and Computation. 2018. Vol. 328. P. 243-246.

We present a general method of solving the Cauchy problem for a linear parabolic partial differential equation of evolution type with variable coefficients and demonstrate it on the equation with derivatives of orders two, one and zero. The method is based on the Chernoff approximation procedure applied to a specially constructed shift operator. It is proven that approximations converge uniformly to the exact solution.
