Аннотация:We consider difference schemes for the heat equation with nonlocal boundary conditions containing
a parameter γ > 1 . Neither the original problem nor its approximating difference scheme is stable in
the initial values. An algorithm is proposed to construct the stability boundaries in subspaces generated
by stable harmonics. Examples of stability boundaries are given for two-layer schemes with various
weights.
Keywords: difference scheme, nonlocal boundary conditions, stability boundaries
