Nonexistence of positive singular solutions for a class of semilinear elliptic systems

Electron. J. Differ. Equ. 1996(8), (1996)

Summary

Summary: We study nonexistence and removability results for nonnegative sub-solutions to $$\left. \eqalign{ \Delta u =\& a(x) v^p \cr \Delta v =\& b(x) u^q \cr} \right\} {\rm in } \Omega \subset R^N,\quad N\ge 3\,, $$ where $p\geq 1, q\geq 1, pq$, and a and b are nonnegative functions. As a consequence of this work, we obtain new results for biharmonic equations.
