摘要：
This paper is concerned with the study of the existence results to the obstacle problem associated with the equation having degenerate coercivity, whose prototype is given by: {- div(b(vertical bar u vertical bar)vertical bar del u vertical bar(p-2)del u) + d(vertical bar u vertical bar)vertical bar del u vertical bar(p) = f(x, u) in Omega, u = 0 on partial derivative Omega, where Omega is a bounded open set of R-N (N >= 2), with 1 < p < N, and f (., s) satisfying some growth condition. We show the existence of entropy solutions for this non-coercive unilateral elliptic equation, and we will conclude some regularity results.
