Spectral properties of singular Sturm-Liouville operators with indefinite weight sgn x [PDF]

, 2007
We consider a singular Sturm-Liouville expression with the indefinite weight sgn x. To this expression there is naturally a self-adjoint operator in some Krein space associated.

Existence Result for a Class of Elliptic Systems with Indefinite Weights in R2

Boundary Value Problems, 2008
We obtain the existence of a nontrivial solution for a class of subcritical elliptic systems with indefinite weights in R2. The proofs base on Trudinger-Moser inequality and a generalized linking theorem introduced by Kryszewski and Szulkin.

From Dynkin diagram symmetries to fixed point structures [PDF]

, 1995
Any automorphism of the Dynkin diagram of a symmetrizable Kac-Moody algebra induces an automorphism of the algebra and a mapping between its highest weight modules.

Multiplicity of Solutions for Gradient Systems Using Landesman-Lazer Conditions

Abstract and Applied Analysis, 2010
We establish existence and multiplicity of solutions for an elliptic system which presents resonance at infinity of Landesman-Lazer type. In order to describe the resonance, we use an eigenvalue problem with indefinite weights.

Geometric Engineering of N=2 CFT_{4}s based on Indefinite Singularities: Hyperbolic Case

, 2003
Using Katz, Klemm and Vafa geometric engineering method of $\mathcal{N}=2$ supersymmetric QFT$_{4}$s and results on the classification of generalized Cartan matrices of Kac-Moody (KM) algebras, we study the un-explored class of $\mathcal{N}=2$ CFT$_{4}$s

Transfer of K-types on local theta lifts of characters and unitary lowest weight modules [PDF]

, 2012
In this paper we study representations of the indefinite orthogonal group O(n,m) which are local theta lifts of one dimensional characters or unitary lowest weight modules of the double covers of the symplectic groups. We apply the transfer of K-types on
