Department of Mathematics
Welcome to the web page of the Mathematics Department of the Mathematics Institute of the Federal University of Rio de Janeiro. The Mathematics Department offers undergraduate courses in its Bacharalado, its Licenciatura, as well as diverse service courses for other departments of the university. Together with the other departments of the Mathematics Institute, the Mathematics Department offers post-graduate programmes in Mathematics and Mathematical Teaching. The teaching staff of the Mathematics Institute is actively involved in mathematical research and outreach programmes. The excellence of our researchers provides a fertil academic atmosphere with strong interactions with the international mathematical community.

Title: The Abresch-Rosenberg shape operator and applications
Abstract: In this talk we use a Codazzi pair defined in any constant mean curvature (CMC) surface immersed in the homogeneous 3-manifolds E(k,t) to compute a Simons formula for the CMC surfaces. In particular, we will show two applications of this formula: 1. We will show some pinching theorems for CMC surfaces in E(k,t). 2. We will define the CMC surfaces with finite Abresch-Rosenberg total curvature immersed in E(k,t) and we will get a bound of the first eigenvalue of any Schrodinger operator defined on these surfaces. In particular, this estimation gives a bound for the stability operator of any compact CMC surface. This is a joint work with Jose M. Espinar.
