Supercritical Lane-Emden equation on a cone with an inhomogeneous Dirichlet boundary condition

Sho Katayama

We consider the Lane-Emden equation with a supercritical nonlinearity with an inhomogeneous Dirichlet boundary condition on an infinite cone. Under suitable conditions for the boun…

Supercritical Henon type equation with a forcing term

Kazuhiro Ishige, Sho Katayama

This paper is concerned with the structure of solutions to the elliptic problem for an Henon type equation with a forcing term. Under suitable assumptions on the forcing term, we g…
