Three-layer semi-discrete schemes for second order evolution equations are studied in the Hilbert space using Chebyshev polynomials. A priori estimates are proved for approximate solutions, as well as for difference analogues of first and second orde

In the present work the Cauchy problem for an abstract evolution equation with a Lipschitz-continuous operator is considered, where the main operator represents the sum of positive definite self-adjoint operators. The fourth-order accuracy decomposit

In the present paper, we use the perturbation algorithm to reduce a purely implicit four-layer semi-discrete scheme for an abstract evolutionary equation to two-layer schemes. An approximate solution of the original problem is constructed using the s
