The weighted periodic-parabolic degenerate logistic equation
D. Aleja, I. Antón, J. López-Gómez
The main goal of this paper is twofold. First, it characterizes the existence of positive periodic solutions for a general class of weighted periodic-parabolic logistic problems of…
Axiomatization of the degree of Fitzpatrick, Pejsachowicz and Rabier
Julián López-Gómez, Juan Carlos Sampedro
In this paper we prove an analogue of the uniqueness theorems of Führer and Amann and Weiss to cover the degree of Fredholm operators of index zero of Fitzpatrick, Pejsachowicz and…
New Analytical and Geometrical Aspects of the Algebraic Multiplicity
Julián López-Gómez, Juan Carlos Sampedro
This paper reveals some new analytical and geometrical properties of the generalized algebraic multiplicity, , introduced in [7, 5] and further developed in [20, 23, 24]. In par…
General uniqueness results for large solutions
Julián López-Gómez, Luis Maire, Laurent Veron
We give a series of very general sufficient conditions in order to ensure the uniqueness of large solutions for --u + f (x, u) = 0 in a bounded domain where f : x R $\ri…
The Picone identity: A device to get optimal uniqueness results and global dynamics in Population Dynamics
Sergio Fernández-Rincón, Julián López-Gómez
This paper infers from a generalized Picone identity the uniqueness of the stable positive solution for a class of semilinear equations of superlinear indefinite type, as well as t…
Multiplicity of subharmonics in a class of periodic predator-prey Volterra models
Julián López-Gómez, Eduardo Muñoz-Hernández
This paper ascertains the global topological structure of the set of subharmonics of arbitrary order of the periodic predator-prey model introduced in López-Gómez, Ortega and Tineo…
