15h15-16h05 Luís Sanchez, DMFCUL: Some arguments of topological nature with applications in Nonlinear Analysis.

Abstract: When methods of Nonlinear Analysis are applied to differential equations, arguments of topological nature often occur. In this talk differential equations are not mentioned; instead we concentrate in surveying a number of devices that have persistently appeared in the literature in the last five decades, involving some topological argument. The kind of reasonings at stake make appeal to connectedness or to some property of non-empty intersection of two geometrical objects. Such arguments play a key role in critical point theory and in bifurcation theory. In the backgound we invoque the Brouwer fixed point theorem, the theorem of Poincaré-Miranda and degree theory.

16h25-17h15 Anca-Maria Toader, DMFCUL: Microstructures - a symbiosis between PDEs, Differential Geometry and Programming.

Abstract: Microstructures model the internal patterns that compose real world bodies at the microscopic level. They determine the way in which the body (or the macrostructure) responds to external loads and the way in which it fulfills the task for which it was designed to. The microscale is infinitesimal with respect to the macroscale. At each point of the body the material is supposed to be locally periodic. The macroscopic behaviour of the body, according to the homogenization theory, is described in terms of the solution of a PDE with periodicity conditions, called cellular problem. Imposing periodicity conditions in the cellular problem is equivalent to solving a PDE on a differential manifold defined as the quotient of R^3 with respect to the periodicity group. The solution can be viewed as a multi-function defined on this manifold which is a flat torus non immersible in R^3. For numerical simulations, adapted methods should be developed : meshes and finite elements on the torus are challenges to be attained with a new home made C++ Library called ManiFEM. The motivation of developing such a software able to deal with finite elements on manifolds and some examples will be presented in order to gain fans and users.

Imagem ilustrativa do curso, acompanhada de várias informações úteis

Um curso dirigido ao público em geral e a estudantes de arte ou ciência (a partir dos 16 anos), com interesse em desenho de observação, ilustração e biologia, com ou sem experiência em desenho.

The objective of this course is to introduce participants to the details of communication and writing scientific publications.

The objective of this course is to introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

This course aims to evidence the importance of natural history collections for the study of biodiversity, to show new tools and approaches to extract and disseminate biodiversity data from natural history collections and to increase awareness of young researchers for the scientific and cultural value of Natural History Museums.

The course aims at providing an introduction to stable isotopes ratios as tools to understand global, ecosystem and community level bio/geo cycles; light isotopes: H, N, C, O and S isotopes, geo cycles and ecological significance; sampling and analytical methodologies in stable isotope analysis.

EvoS aims at turning evolutionary theory into a common language to areas that pertain to the natural world, including human affairs.

The course SoilEco aims at introducing attendants to an updated state of the art of diversity of the soil biota and the functional roles played by soil organisms in key ecological processes.

In this course, we promote a multidisciplinary approach presenting the most recent findings on the topic and challenging the traditional way of considering symbiotic associations as exceptions and not as the rule.

The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.
