Abstract: Recently we were able to look at this classical differential topology result from the prospect of category theory.  In this talk I will report our findings. Joint work Dr. Lino Grama and Dr. Leonardo Cavenaghi.

Abstract: I will give a brief survey on recent works around the Shafarevich conjecture on holomorphic convexity of the universal cover of quasi-projective varieties. My main focus will be the nilpotent case and contributions of Green-Griffiths-Katzarkov and Aguilar-Campana. Some tools of the proof will be given. Time permitting, I will give some comments on the reductive case.

Abstract: We will present some properties of Lagrangian subvarieties of irreducible symplectic (or hyper-Kaehler) manifolds. We will focus on their interaction with a Lagrangian fibrations of the ambient hyper-K\"ahler and the albanese dimension of Lagrangian surfaces.

AbstractWe begin by recalling classical works of Donaldson and Simpson. Based on these works we take  a new look at generalized geometries and "Hodge theory" connected with them.
