We consider nondivergent elliptic and parabolic equations of the second order whose leading coefficients satisfy the uniform Lipschitz condition. We find a sufficient condition for the removability of a compact set with respect to these equations in the space of Hölder functions.

On the smoothness of a solution of the first boundary-value problem for second-order degenerate elliptic-parabolic equations

Gadjiev T. S., Gasimova E. R.

Ukr. Mat. Zh. - 2008. - 60, № 6. - pp. 723–736

In this work, the first boundary-value problem is considered for second-order degenerate elliptic-parabolic equation with, generally speaking, discontinuous coefficients. The matrix of senior coefficients satisfies the parabolic Cordes condition with respect to space variables. We prove that the generalized solution to the problem belongs to the Holder space C 1+λ if the right-hand side f belongs to Lp, p > n.
