Sir Michael Atiyah em Portugal para Pedro Nunes Lectures

Um dos maiores nomes da Matemática contemporânea estará em Portugal para as Pedro Nunes Lectures de 29 de Março a 6 de Abril. Michael Francis Atiyah, britânico de origem libanesa, é detentor da Medalha Fields (1966), do Prémio Abel (2004) e da medalha Copley (1988), outorgada pela Royal Society de Londres. As suas contribuições matemáticas, bem como a sua luta pelo desarmamento nuclear, levaram-no a receber da rainha da Inglaterra o título de Sir em 1983 e a receber a Ordem do Mérito em 1992.

O matemático estará em Lisboa, Braga, Porto e Coimbra para falar dos seus trabalhos em análise, geometria e topologia, de relações entre matemática e física, bem como da profissão de matemático.

Atiyah foi professor na universidade de Oxford e no Instituto de Estudos Avançados, em Princeton, director do Trinity College e do Isaac Newton Institute for Mathematical Sciences, ambos em Cambridge, presidente da Royal Society de Londres e Chanceler da Universidade de Leicester. Actualmente é professor honorário da Universidade de Edimburgo.

As Pedro Nunes Lectures são uma iniciativa do Centro Internacional de Matemática, em colaboração com a Sociedade Portuguesa de Matemática e com o apoio da Fundação Calouste Gulbenkian.

Programa das Pedro Nunes Lectures

Geometric Models of Matter
29 de Março, 17h30 – Fundação Calouste Gulbenkian, Lisboa
Auditório 2

Abstract: Einstein always wanted to supplement his beautiful geometric theory of general relativity by a parallel treatment of matter. Much has happened in physics since Einstein’s time, with geometry playing an important part. In my lecture I will put forward some speculative new ideas in this area.

An unsolved problem in elementary Euclidean geometry
31 de Março, 11h30 – Universidade do Minho
Anfiteatro da Escola de Ciências, Campus de Gualtar
Abstract: I will describe a very simple problem about n distinct points in Euclidean 3 dimensional space. The problem is still unsolved after more than 10 years. The problem has a number of interesting contacts with theoretical physics, which may help in its solution.

Topology and quantum physics
4 de Abril, 15h00 – Universidade do Porto
Edifício da Matemática da FCUP
Abstract: Geometry and Physics have been closely linked, at least from the time of Galileo and Newton. Forces turn straight line motion into curved paths and the fundamental link between curvature and force persists into Maxwell’s theory of Electro-Magnetism and Einstein’s theory of General Relativity. 20th century Physics was dominated by Quantum Mechanics, and it took a long time to realize that this has close links with Topology, the branch of Geometry where measurement is unimportant and which is typified by the study of knots. I will try to explain this story in non-technical language, using only high school geometry and physics.

The index theory of Fredholm operators
6 de Abril, 14h30 – Universidade de Coimbra
Sala Pedro Nunes do Departamento de Matemática
Abstract: Fredholm operators are bounded operators in Hilbert space which, together with their adjoints, have a finite-dimensional null space. The index is the difference of the dimensions of these two null spaces, and is invariant under continuous perturbation. Fredholm operators arise naturally from elliptic differential operators, and the computation of the index is a classical problem. I will discuss this story in general terms and give simple examples. I will also introduce a number of variations on the theme.
