Brief description

The most realistic parabolic models in Population Dynamics, Reaction-Diffusion equations and Fluid Dynamics are those incorporating spatial and temporal heterogeneities in its formulation, as in Nature most of phenomenology’s are seasonal and spatial heterogeneities are the general rule, for as the amount of solar energy received depends on the precise location. In this project we are going to analyze the effects of the spatial and temporal heterogeneities on the dynamics of some paradigmatic models in Ecology, Reaction-Diffusion and Fluid Dynamics, including periodic-parabolic predator prey and competition systems. Among the expected results are the following: (a) establishing that seasonal effects in predator-prey systems provoke chaos; (b) finding out what are the aspects of the spatial heterogeneities provoking complexity; (c) finding out the optimal conditions for the existence of a priori bounds in superlinear indefinite BVP’s.

• 27 November 2023. Four IMI members and four members of its Scientific Committee are in the lists of the most highly cited scientists worldwide, published by Stanford University.  The selection is based on the top 100,000 scientists by c-score or a percentile rank of 2% or above in the sub-field. The four IMI members mentioned are Juan Luis Vázquez Suárez, Julián López-Gómez, Jesús Ildefonso Díaz Díaz and Francisco Javier Montero de Juan. Also appearing in the same lists are IMI Scientific Committee members Paul Rabinowitz, Simon Donaldson, Herbert Amann and Dikran Dikranjan.
