Title: " On the slope of fibred surfaces "
Abstract: Let f be a surjective morphism with connected fibres from a projective smooth surface S to a projective smooth curve B, with genus of the general fibre F g>= 2. Let us suppose that f is not isotrivial (i.e. the smooth fibres are not mutally isomorphic) and that it is relatively minimal (i.e. the relative canonical divisor K_S-f^*K_B=K_f is realtively nef). The slope of f , called s(f), is defined to be the ratio between {K_f}^2 and the relative Euler characteristic \chi_f. In this talk I will review old an new results on the serach of lower bounds for the slope, and I will discuss the methods used for this results, which are due to (in chronological order) Xiao, Cornalba-Harris, Moriwaki, Konno and Lu-Zuo. Eventually I will discuss a recent result obatained in collaboration with a Ph.D. student of mine, Enea Riva, alongside with some possible strategy to improve these results.

Title: " Schauder estimates for any taste. "
Abstract:
So-called Schauder estimates are a standard tool in the analysis of linear elliptic and parabolic PDE. They have been originally obtained by Hopf (1929, interior case), and by Schauder and Caccioppoli (1934, global estimates). The nonlinear case is a more recent achievement from the ’80s (Giaquinta & Giusti, Ivert, Lieberman, Manfredi). All these classical results hold in the uniformly elliptic framework. I will present the solution to the longstanding problem, open since the ‘70s, of proving estimates of such kind in the nonuniformly elliptic setting. I will also cover the case of nondifferentiable functionals and provide a complete regularity theory for a new double phase model. From joint work with Giuseppe Mingione (University of Parma).

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.
