Abstract: | We prove an assertion about the increase of a solution, weak in the sense of Trudinger, to the Dirichlet problem for m-Hessian equations with the righthand side in L
q
, q > n(n + 1)/(2m). We estimate the ratio between the increment of the solution along the normal and the distance to the boundary of a domain.
This assertion is also proved for some class of degenerate linear elliptic equations of second order. Bibliography: 7 titles.
