A RESULT ON THE BIFURCATION FROM THE PRINCIPAL EIGENVALUE OF THE Ap-LAPLACIAN

We study the following bifurcation problem in any bounded domain Ω in IR :   Apu := − N ∑ i,j=1 ∂ ∂xi  ( N ∑ m,k=1 amk(x) ∂u ∂xm ∂u ∂xk ) p−2 2 aij(x) ∂u ∂xj   = λg(x)|u|p−2u+ f(x, u, λ), u ∈ W 1,p 0 (Ω). We prove that the principal eigenvalue λ1 of the eigenvalue problem { Apu = λg(x)|u|p−2u, u ∈ W 1,p 0 (Ω), is a bifurcation point of the problem mentioned above.

Bifurcation from a degenerate simple eigenvalue

It is proved that a symmetry-breaking bifurcation occurs at a simple eigenvalue despite the usual transversality condition fails, and this bifurcation from a degenerate simple eigenvalue result complements the classical one with the transversality condition. The new result is applied to an imperfect pitchfork bifurcation, in which a forward transcritical bifurcation changes to a backward one wh...

The ∞−Laplacian first eigenvalue problem

We review some results about the first eigenvalue of the infinity Laplacian operator and its first eigenfunctions in a general norm context. Those results are obtained in collaboration with several authors: V. Ferone, P. Juutinen and B. Kawohl (see [BFK], [BK1], [BJK] and [BK2]). In section 5 we make some remarks on the simplicity of the first eigenvalue of ∆∞: this will be the object of a join...

Optimizing the principal eigenvalue of the Laplacian in a sphere with interior traps

The method of matched asymptotic expansions is used to calculate a two-term asymptotic expansion for the principal eigenvalue λ(ε) of the Laplacian in a three-dimensional domain Ω with a reflecting boundary that contains N interior traps of asymptotically small radii. In the limit of small trap radii ε → 0, this principal eigenvalue is inversely proportional to the average mean first passage ti...

The smallest eigenvalue of the signless Laplacian

Recently the signless Laplacian matrix of graphs has been intensively investigated. While there are many results about the largest eigenvalue of the signless Laplacian, the properties of its smallest eigenvalue are less well studied. The present paper surveys the known results and presents some new ones about the smallest eigenvalue of the signless Laplacian.
