A global bifurcation result for a semilinear elliptic equation
AbstractWe consider the problem{−Δu=up+λuin A,u>0in A,u=0on ∂A, where A is an annulus of RN, N⩾2, p∈(1,+∞) and λ∈(−∞,0]. Recent results (Gladiali et al., 2009 [5]) ensure that there exists a sequence of values of the exponent {pk} at which nonradial bifurcation from the radial solution occurs.

Dimension of the set of positive solutions to nonlinear equations and applications
We study the covering dimension of the set of (positive) solutions to various classes of nonlinear equations involving condensing and A-proper maps. It is based on the nontriviality of the fixed point index of a certain condensing map or on oddness ...

Concentration and dynamic system of solutions for semilinear elliptic equations
In this article, we use the concentration of solutions of the semilinear elliptic equations in axially symmetric bounded domains to prove that the equation has three positive solutions. One solution is y-symmetric and the other are non-axially symmetric.

On oscillating radial solutions for non-autonomous semilinear elliptic equations
We consider semilinear elliptic equations of the form $ \Delta u + f(|x|, u) = 0 $ on $ {\mathbb{R}}^{N} $ with $ f(|x|, u) = q(|x|)g(u) $. These type of equations arise in various problems in applied mathematics, and particularly in the study of ...

A singular perturbation result for a class of periodic-parabolic BVPs
In this article, we obtain a very sharp version of some singular perturbation results going back to Dancer and Hess [Behaviour of a semilinear periodic-parabolic problem when a parameter is small, Lecture Notes in Mathematics, Vol. 1450, Springer-Verlag,
