Soluciones con soporte compacto para ciertos problemas semilineales.

Jesús Ildefonso Díaz Díaz (1979)

Collectanea Mathematica

In this paper we prove that some classes of semilinear elliptic problems, formulated in very general terms by using the theory of maximal monotone graphs, admit a finite propagation speed. More concretely we show that if the data of these problems have compact supports, then the same happens to their solutions. These same thechniques will also be applied to some evolution problems. The first results in this direction are due to H. Brézis and to O. Oleinik & A. S. Kalashnikov & C. Yuilin...

Solutions for Toda systems on Riemann surfaces

Jiayu Li, Yuxiang Li (2005)

Annali della Scuola Normale Superiore di Pisa - Classe di Scienze

In this paper we study the solutions of Toda systems on Riemann surface in the critical case, proving a sufficient condition for existence.

Solutions to a perturbed critical semilinear equation concerning the N -Laplacian in N

Elliot Tonkes (1999)

Commentationes Mathematicae Universitatis Carolinae

The aim of this paper is to study the existence of variational solutions to a nonhomogeneous elliptic equation involving the N -Laplacian - Δ N u - div ( | u | N - 2 u ) = e ( x , u ) + h ( x ) in Ω where u W 0 1 , N ( N ) , Ω is a bounded smooth domain in N , N 2 , e ( x , u ) is a critical nonlinearity in the sense of the Trudinger-Moser inequality and h ( x ) ( W 0 1 , N ) * is a small perturbation.

Solvability for semilinear PDE with multiple characteristics

Alessandro Oliaro, Luigi Rodino (2003)

Banach Center Publications

We prove local solvability in Gevrey spaces for a class of semilinear partial differential equations. The linear part admits characteristics of multiplicity k ≥ 2 and data are fixed in G σ , 1 < σ < k/(k-1). The nonlinearity, containing derivatives of lower order, is assumed of class G σ with respect to all variables.
