Abstract:

A boundary value problem to a class of elliptic equations with lower order terms and degenerate coercivity is studied in this paper. With help of De Giorgi iterative technique and Boccardo-Brezis's test function, the L estimate to weak solutions of the problem is obtained. Based upon the uniform L bound, the existence of bounded solution is proved.

Key words: Elliptic equations, Degenerate coercivity, Lower order terms, L regularity
