Prykladni Problemy Mekhaniky i Matematyky| Zusammenfassung: | Lower bounds estimates for the Lebesgue measure of sublevel set of smooth function have been established if the result of the differential expression of the third order is not equal to zero. The partial cases when the differential expression allows Polya factorization are considered. We done application of the obtained results to prove metric estimates for the small denominators that arise in the study of three-point problems for loaded partial differential equations with variables coefficients.
