An estimate of Green's function of the problem of bounded solutions in the case of a triangular coefficient

V. G. Kurbatov, I. V. Kurbatova

An estimate of Green's function of the bounded solutions problem for the ordinary differential equation $x^{'} (t) - B x (t) = f (t)$ is proposed. It is assumed that the matrix coefficient $B…

Computation of a function of a matrix with close eigenvalues by means of the Newton interpolating polynomial

V. G. Kurbatov, I. V. Kurbatova

An algorithm for computing an analytic function of a matrix $A$ is described. The algorithm is intended for the case where $A$ has some close eigenvalues, and clusters (subsets) of…
