On a problem of resonance with exponential non linearity

B. B. Manna, P. N. Srikanth

We have considered the following semi linear elliptic problem on the unit disk $B$ $- Δ u = λ_{1} u + e^{u} + f$ in $B$ with the Dirichlet boundary condition and $f$ satisfying the followin…

On the solutions of a singular elliptic equation concentrating on two orthogonal spheres

B. B. Manna, P. N. Srikanth

Let $A = {x \in R^{2 m} : 0 < a < ∣ x ∣ < b}$ be an annulus. Consider the following singularly perturbed elliptic problem on $A$ \begin{equation} \begin{array}{lll} -\eps^2{\De u} + |x|^…

A Reduction Method for Semilinear Elliptic Equations and Solutions Concentrating on Spheres

Filomena Pacella, P. N. Srikanth

We show that any general semilinear elliptic problem with Dirichlet or Neumann boundary conditions in an annulus A in R^2m ;m >1, invariant by the action of a certain symmetry grou…
