Determining a modular interpretation of birational models arising from the MMP on Mg, the moduli space of genus g curves, is known as the Hassett-Keel program. The first few steps are well-understood yet the program remains quite incomplete in general for any genus g > 3. In this talk, we will discuss the complete Hassett-Keel program in genus 4. This is joint work with Kenneth Ascher, Yuchen Liu, and Xiaowei Wang.

Let $f : X \to Y$ be a fibration between two projective manifolds. The Iitaka's conjecture predicts that the Kodaira dimension of $X$ is larger than the sum of the Kodaira dimension of $X$ and the Kodaira dimension of the generic fiber. We explain a proof of the Iitaka conjecture for algebraic fiber spaces over abelian varieties or projective surfaces.
It is a joint work with Mihai Paun.

I will introduce the concept of K-moduli illustrated by some examples of moduli spaces and related comparisons with GIT and wall-crossing phenomenon.

Aim of the lecture is to give an introduction to $K3$ surfaces, that are special algebraic surfaces with an extremely rich geometry. The most easy example of such a surface is the Fermat quartic in complex three-dimensional space.
The name $K3$ was given by André Weil in 1958 in honour of the three remarkable mathematicians: Kummer, Kähler and Kodaira and of the beautiful K2 mountain at Cachemire.
The topics of the lecture are the following:

* $K3$ surfaces in the Enriques-Kodaira classification.
* Examples; Kummer surfaces.
* Basic properties of $K3$ surfaces; Torelli theorem and surjectivity of the period map.
* The study of automorphisms on $K3$ surfaces: basic facts, examples.
* Symplectic automorphisms of $K3$ surfaces, classification, moduli spaces.[-]
