Metric estimates of small denominators in nonlocal boundary value problems. (Russian. English summary) Zbl 1336.35255
Summary: The metric estimates of small denominators at the analysis of nonlocal boundary value problems for a parabolic-hyperbolic equation are established. We use the metric approach to prove these estimates.
