摘要

We study quasilinear degenerate singular elliptic equations of the type -Δ_pu= = uP(s up(s)-1 in a smooth bounded domain Ω in R~N = R~kx R~(N-k), x (y,z) ∈ R~k x R~(N-k) 2 < k < N and N > 3, 1 < p < 2, 0 < s < p, 0 < t < s and p~* (s) = P(n-s)/(n-p). We study existence of solutions for t < s, non-existence in a star-shaped domain for t s and s < k((p-1/p)). We also show that the solution is in C~(1'a)(Ω) for some 0 < a < 1 provided t < k/N ((p-1/p)) The regularity of the solution can be improved to the class W~(2'p)(Ω) when t < k((p-1/p)). We also study some properties of the set of degeneracy in a cylindrically symmetric domain using the method of symmetry.
