Title: Derived categories, an introduction Abstract:Derived categories were introduced by Grothendieck and Verdier around 1960, and since then they have been widely used in algebraic geometry. In this talk, I will try to motivate their use and…

ION: Where Mathematics matter for FinTech Innovation – ION Group (ION Group)
With Innovation as core founding value, ION is a global company that in its twenty years of activity has delivered…
On the (non)existence of degenerate phase-shift localised solution in KG (and dNLS) nonlocal lattices – Simone Paleari (Università degli Studi di Milano)
We study the existence of, low amplitude, phase-shift multibreathers for small values of the linear coupling in Klein-Gordon chains with interactions beyond the classical nearest-neighbor (NN) ones. In the proper parameter regimes,…
On the statistics of extremes for dynamical systems – Mark Holland (University of Exeter)
The study of successive maxima (or minima) for stochastic processes is called Extreme Value Theory. It is extensively used in risk analysis to estimate probabilities of rare events and extremes, e.g. floods; hurricanes; market crashes and general…
Divisibility questions in commutative algebraic groups – Laura Paladino (Università di Pisa)

Double phase problems with variable growth – Vicentiu Radulescu (Inst. Math. of the Romanian Academy & University of Craiova)
We consider several classes of double phase variational integrals driven by nonhomogeneous potentials. We study the associated Euler equations and we highlight some new properties. We point out concentration phenomena of the spectrum, nonexistence…
Entropia topologica su superfici complesse – Giacomo Mezzedimi (Hannover University)
Titolo:Entropia topologica su superfici complesse Abstract: L’entropia topologica misura il ‘disordine’ creato da una trasformazione di uno spazio metrico compatto, ed e’ in generale molto difficile da calcolare. Nel caso pero’ di automorfismi su…
Approximate convexity principles and applications to PDEs in convex domain – Marco Squassina (Univ Brescia)
We obtain approximate convexity principles for solutions to some classes of nonlinear elliptic partial differential equations in convex domains involving approximately concave nonlinearities. Furthermore, we provide some applications to some…
MATLAB Tools for Large-Scale Linear Inverse Problems – James Nagy (Department of Mathematics, Emory University)
Inverse problems arise in a variety of applications: image processing, finance, mathematical biology, and more. Mathematical models for these applications may involve integral equations, partial differential equations, and dynamical systems, and…
