  • Title: Variedades riemannianas planas e reduzibilidade
  • Speaker: Prof. Andrzej Derdzinski
  • Abstract: Em um artigo publicado no Journal of Pure and Applied Algebra (1991)Hiss e Szczepanski provaram um teorema que estabelece a reduzibilidade da representação de holonomia para toda variedade riemanniana compacta plana de dimensão maior que um, com a conclusão adicional que o subespaço invariante não nulo e próprio do espaço tangente pode ser escolhido de tal modo que ele seja gerado por um subconjunto do reticulado associado à variedade dada.O que nos interessa aqui são algumas consequências geométricas do resultado mencionado acima e as suas ramificações no contexto dum outro teorema,  obtido pelos mesmos autores em um artigo de 1997, segundo o qual em certas
    dimensões maiores que 20 existem variedades riemannianas compactas planas cujo primeiro numero de Betti é igual a zero.

  • Title: Geometric Stacks and Groupoids
  • Speaker: Joel Villatoro
  • Abstract: This talk will survey some folklore theorems about the interaction between the theory of Lie groupoids
    and geometric stacks on the site of smooth manifolds. To do this, a more general theorem
    about the relationship between geometric stacks on a site and internal groupoids will be discussed.
    I will show how considering alternative sites can be applied to studying Morita equivalences of Lie groupoids equipped with additional geometry.

  • Title: Holonomic submanifolds
  • Speaker: Marcos Dajczer (IMPA)
  • Abstract:An isometric immersion of a Riemannian manifold into a space form is said to be holonomic if the manifold carries
    a global system of orthogonal coordinates such that at any point the coordinate vector fields diagonalize the second fundamental form.  In this talk I will discuss several results, ranging from classical to recent, about these submanifolds.


  • April 25, 2018 at 15h
  • Title: A classification of semistable Higgs bundles on Calabi-Yau manifolds
  • Speaker: Valeriano Lanza
  • Abstract: In a recent work by Biswas, Bruzzo, Graña Otero and Lo Giudice it is shown that on a simply connected Calabi-Yau manifold there is no polystable Higgs bundle with nontrivial Higgs field. The same is not true for semistable Higgs bundles, as examples can be easily provided. Nevertheless, Higgs fields for semistable Higgs bundles on Calabi-Yau
    manifolds are strongly constrained. The goal of this talk is to discuss the situation for bundles of low rank,
    for which we are able to provide a complete classification of possible Higgs fields. Furthermore, we provide also an application to a conjecture about a particular class of semistable Higgs bundles (the so-called curve
    semistable ones), which is proved for K3 and related surfaces.

  • Title: Robust index bounds for minimal hypersurfaces in compact symmetric spaces and isoparametric submanifolds
  • Speaker: Dr Ricardo Mendes (Universitaet zu  Koeln)
  • Abstract: (joint work with C. Gorodski and M. Radeschi)
    It has been conjectured by Marques-Neves-Schoen that, for every compact Riemannian manifold (M,g) with positive Ricci curvature, there exists a positive constant C such that every closed minimal hypersurface of M has Morse index bounded below by C times its first Betti number. This conjecture has been verified for the spheres by Savo, for every compact rank
    one symmetric space by Ambrozio-Carlotto-Sharp, and for every compact symmetric space (with the index replaced with index plus nullity) by Mendes-Radeschi. In the present work we expand this list of examples to infinitely many isoparametric hypersurfaces of spheres and their focal manifolds. We also show that, for all our new examples, as well as many of the
    previously known examples (including the spheres), such an index bound remains valid after any small deformation of the ambient metric g.

    and singular foliation of codimension 1. Then some applications of transnormal functions in Physics
    are provided, such as  propagation of the wildfire.
