Declaration of intent
This summer school series aims at training their participants in key strategic problems in mathematics and their applications, with the core idea that theory and applications strengthen each other. The school is focused in training of young researchers whilst opening new fields for senior ones.
The Hypatia Graduate Summer School will consist in two keynote courses on subjects of exceptional promise and scientific importance delivered by highly distinguished speakers in the area plus a high-level colloquium on a complementary subject.
The Hypatia Graduate Summer School will be developed in an informal atmosphere based on discussions, exchange of ideas and critical analysis of results. Moreover, to honour its namesake, it is committed to work under a friendly gender perspective that highlights the role of women in mathematics and encourages and helps the participation and promotion of young female researchers at a professional level.

COURSES
COURSE 1: Contact geometry and the many facets of complexity of hydrodynamics
Lecturer: Eva Miranda (UPC-CRM) / Daniel Peralta (ICMAT)
Abstract:
In this course we will unveil various connections between three seemingly unconnected topics: contact geometry, fluid mechanics, and Turing machines.
The point of departure will be Euler’s equations with a focus on the study of stationary solutions. Our constructions combine techniques from various areas of mathematics that we will thoroughly analyze in this course. An important ingredient will be the close inspection of various notions of complexity of our constructions: dynamic, computational and logical. Several applications to Celestial mechanics will also be discussed.

COURSE 2: Symbolic Dynamics in Celestial Mechanics
Lecturer: Susanna Terracini (Dipartimento di Matematica “Giuseppe Peano”)
Abstract:
it is part of the mathematical folklore that Dynamical Systems featuring many nonlinear interactions should display chaotic behavior and possess complex dynamics, whatever this means.
On the other hand, for natural systems, this lacks a rigorous statement and even more, a rigorous proof, specially when we are leaving the perturbative setting.
The purpose of the minicourse is to illustrate how to contstruct complex trajectories by the use of global variational methods in some relevant models from Celestial Mechanics.

The dynamics of computation
HYPATIA COLLOQUIUM
DATE: June 6th, 2023
LOCATION: Institut d’Estudis Catalans (IEC)
ABSTRACT:
Computers are dynamical systems, and some dynamical systems can compute. I’ll discuss how Turing machines can be embedded in continuous dynamical systems, making undecidability and uncomputability show up in unexpected places. I’ll also discuss different models of analog computation that have been considered over the years. Finally, I’ll connect dynamics to computational complexity theory, by considering the difficulty of predicting different physical and dynamical systems, some of which have algorithmic “shortcuts” and some of which seem to require explicit simulation.

Cristopher MooreSanta Fe Institute I am a Professor at the Santa Fe Institute. I work on problems at the interface of physics, computer science, and mathematics, such as phase transitions in statistical inference. When the amount of noise in a data set crosses a critical threshold, it can suddenly become impossible to find underlying patterns in it, or even tell if a pattern is really there. This includes finding communities in social and biological networks, or clusters in high-dimensional data, or structure in noisy matrices and tensors. How can we locate these phase transitions, and what informational and computational barriers do they create? I have also worked on phase transitions in search and optimization problems, where problems suddenly become unsolvable when they become too constrained; quantum computation and quantum algorithms for the Graph Isomorphism problem; the computational complexity of predicting physical systems, and of solving systems of equations; percolation, topological defects, and Monte Carlo algorithms; games, tilings, and cellular automata; the stability of financial markets, epidemics in networks, and universality in human language; the combinatorics of proof-of-stake blockchains; and braided orbits in the three-body problem. |
