摘要：
We study the local behavior of bounded local weak solutions to a class of anisotropic singular equations of the kind Sigma(s)(i=1)partial derivative(ii)u Sigma(N)(i=1s+1)partial derivative(i)(A(i)(x, u, del u)) = 0, x is an element of Omega subset of subset of R-N for 1 <= s <= (N -1), where each operator A(i) behaves directionally as the singular p-Laplacian, 1 < p < 2. Throughout a parabolic approach to expansion of positivity we obtain the interior Holder continuity and some integral and pointwise Harnack inequalities.
