DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ADGIS/1/">An
 alysis on singular and non-compact spaces and Lie manifolds</a>\nby Victor
  Nistor (Université de Lorraine\, France) as part of Analysis and Differe
 ntial Geometry International Seminar @ Aveiro\n\n\nAbstract\nI will begin 
 by reviewing some classical results on the analysis on compact manifolds a
 nd on manifolds with conical points (due to Kondratiev and others). It tur
 ns out that many of these classical results generalize to a larger class o
 f singular or non-compact spaces defined using Lie algebroids and Lie mani
 folds. Since we will treat singular spaces by blowing them up to a non-com
 pact manifold\, I will refer in the following only to non-compact manifold
 s.\n\nIn order to obtain the mentioned generalizations\, I will stress the
  role of Lie algebroids and hence of suitable classes of vector fields in 
 modelling the geometry at infinity\, which is at the heart of the definiti
 on of a Lie manifold. As an example\, I will explain how to obtain Fredhol
 m conditions for the natural operators on suitable Lie manifolds. The resu
 lts of this talk are based\, in part\, on joint work with Ammann\, Carvalh
 o\, and Yu.\n

DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ADGIS/3/">On
  the Brunn-Minkovski inequality and sub-Riemannian curvature</a>\nby David
 e Barilari (Università degli Studi di Padova) as part of Analysis and Dif
 ferential Geometry International Seminar @ Aveiro\n\n\nAbstract\nThe class
 ical Brunn-Minkovski inequality in the Euclidean space generalizes to Riem
 annian manifolds with Ricci curvature bounded from below. Indeed this ineq
 uality can be used to define the notion of "Ricci curvature bounded from b
 elow" for more general metric spaces. A class of spaces which do not satis
 fy this more general definition is the one of sub-Riemannian manifolds: th
 ese can be seen as a limit of Riemannian manifolds having Ricci curvature 
 that is unbounded\, whose prototype is the Heisenberg group. \n\nIn the fi
 rst part of the talk I will discuss about the validity of a Brunn-Minkovsk
 y type inequality in the SR setting. The second part concerns a notion of 
 sub-Riemannian Bakry-Émery curvature and the corresponding comparison the
 orems for distortion coefficients. The model spaces for comparison are var
 iational problems coming from optimal control theory.\n
