On symmetry results for elliptic equations with convex nonlinearities
Kanishka Perera, Marco Squassina
We investigate partial symmetry of solutions to semi-linear and quasi-linear elliptic problems with convex nonlinearities, in domains that are either axially symmetric or radially…

On the second minimax level for the scalar field equation
Kanishka Perera, Cyril Tintarev
The paper studies eigenfunctions for the scalar field equation on at the second minimax level . Similarly to the well-studied case of the ground state, there is a thres…
