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.
Keywords: equation of mixed type; nonlocal boundary value problem; Borel–Cantelli lemma; Lebesgue measure.
