Existence Results for the Equation $– \Delta u = f(x, u) in \mathbb R^n$

Salvatore A. Marano[1]

(1) Università degli Studi di Catania, Italy

Strong solutions to the class of semilinear elliptic equations $– \Delta u = f(x, u) on the entire space and with possibly supercritical growth for $f(x, \cdot)$ are obtained by mainly using fixed points arguments. The case of discontinuous non-linearities is then examined.

Keywords: Elliptic equations in the whole space, discontinuous non-linearities, strong solutions
