Title: " Analytic GIT spaces vs. Coarse Moduli Spaces – Application to Polystable Vector Bundles "
Abstract:
We introduce analytic GIT quotients as local models for analytic GIT spaces.
These are classifying spaces for isomorphisms classes of polystable points.
GIT spaces are compared to coarse moduli spaces. For polystable holomorphic vector bundles
on compact Kähler manifolds the existence of classifying spaces is shown and the existence
of coarse moduli spaces is discussed.

Title: " Severi varieties of Enriques surfaces "
Abstract: Given a (smooth) projective (complex) surface S and a complete
linear (or algebraic) system of curves on S, one defines the Severi
varieties to be the (possibly empty) subvarieties parametrizing nodal
curves in the linear system, for any prescribed number of nodes. These
were originally studied by Severi in the case of the projective plane.
Afterwards, Severi varieties on other surfaces have been studied, mostly
rational surfaces, K3 surfaces and abelian surfaces, often in connection
with enumerative formulas computing their degrees. Interesting
questions are nonemptiness, dimension, smoothness and irreducibility of
Severi varieties.
In this talk I will first give a general overview and then present
recent results about Severi varieties on Enriques surfaces, obtained
with Ciliberto, Dedieu and Galati, and the connection to a conjecture of
Pandharipande and Schmitt.

Title: " Symmetry results for singular solutions to the p-Laplace equation "
Abstract: In this talk we will consider positive singular solutions to semilinear or quasilinear elliptic
problems. We will deduce symmetry and monotonicity results of the solutions via a careful
adaptation of the moving plane procedure of Alexandrov-Serrin.

Title: INTRODUCTION TO LOEWNER THEORY IN ONE COMPLEX VARIABLE
Title: INTRODUCTION TO LOEWNER THEORY IN ONE COMPLEX VARIABLE
Abstract: Topics of the course belong to Complex Analysis in one complex variable and are mainly related to problems in Conformal Mapping. At the same time, although it is not discussed in the course, the modern Loewner Theory has natural extension to several complex variables. Loewner Theory combines deep results from Complex Analysis with fundamental ideas from Dynamics and Lie Group Theory. It includes, as a special case, the theory of one-parameter semigroups, which is classically known to have important applications to time-homogeneous Markov processes. The course would be primarily useful for those students who are interested in Complex Anal- ysis (one and/or several variables) or whose who wish to refresh and deepen his/hers knowledge in one complex variable. Furthermore, the course is advisable for students in Probabilities, espe- cially for those who are interested in applications of Complex Analysis to Stochastic Processes. Finally, the course would be enjoyable for everybody who is curious to see how ideas and meth- ods from different parts of Analysis can work together in the unit disk of the complex plane.
