Elliptic and Parabolic Equations with Involution and Degeneration at Higher Derivatives

We study the solvability in Sobolev spaces of boundary value problems for elliptic and parabolic equations with variable coefficients presence an involution (involutive deviation) at higher derivatives, both nondegenerate degenerate cases. For under study, we prove existence theorems as well uniqueness regular solutions, i.e., those that have all weak derivatives equation.
