This study is based on applications of the geometric theory of composition operators on Sobolev spaces that permits us to estimate constants of the Poincaré–Sobolev inequalities. On this base we obtain lower estimates of the first non-trivial eigenvalues for Ahlfors-type domains (i.e. quasidiscs). This class of domains includes some snowflake-type domains with fractal boundaries.]]> Mon 18 Mar 2019 10:11:14 KRAT ]]> Integral estimates of conformal derivatives and spectral properties of the Neumann-Laplacian https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000650263 Mon 18 Mar 2019 10:11:13 KRAT ]]>
