Mathematical Physics Group

Department of Mathematics "G. Peano"

The research lines in our group pertain to the study of mathematical structures emerging from fundamental theoretical physics and interdisciplinary applications. In particular, the group members have interests in:

  • General relativity and relativistic theories of gravity, including relativistic positioning; 

  • Calculus  of variations on fiber bundles and related conservation laws; 

  • Geometric structures on (pseudo-)Riemannian manifolds deriving from string theory and holography  (AdS/CFT);

  • Mathematical methods for the exact non-perturbative study of quantum field theories (e.g. localization and integrability);

  • Fluid dynamics and optical non-linear  models, their integrability and singularities, dispersive and Hamiltonian PDEs;

  • Geometric-algebraic and qualitative aspects of differential equations of physical, biological and evolutionary interest.

You can learn about these topics (and others) by attending our seminars and special events that we organize regularly. 

The Department has several openings for various positions every year. Some of the opportunities to join our group are summarized here.

Forthcoming Events

September 11-12, 2025 - QuanTO Lectures

Title: Von Neumann Algebras and Entropy/Energy Inequalities in QFT

Lecturer: Roberto Longo (Roma 2)


Abstract: After a brief introduction to operator algebras, I will present new inequalities concerning entropy and energy; in particular, my recent relative entropy/energy ratio local bound in Quantum Field Theory. This bound is model-independent and rigorous; it follows solely from first principles in the framework of translation-covariant, local Quantum Field Theory on the Minkowski spacetime.

October 2, 2025 - Workshop

Website

Title: Extremal Volumes and Related Functionals in Physics and Geometry


Speakers: Edoardo Colombo (UniTo), Matteo Kevin Crisafio (UniTo), Elia Fusi (UniTo), James Sparks (Oxford) 


The study of extremal volumes and related functionals lies at the intersection of modern geometry and theoretical physics, with deep connections to problems in Kähler geometry, K-stability, special holonomy, calibrations and supersymmetric field theories. These objects often provide variational characterizations of structures of central importance in both mathematics and physics.

The aim of the workshop is to bring together researchers from these different perspectives to foster dialogue and interdisciplinary collaboration. The program will feature two introductory lectures, complemented by talks on more specialised topics.

This one-day event is intended as both an introduction to current developments in the field and a platform to exchange ideas across geometry and physics. 


Registration: There is no registration fee, but we kindly ask you to send an email to lorenzo.ruggeri@unito.it so we can keep track of attendance. In the evening, we will have an informal dinner: if you would like to join, just let us know in your email at your earliest convenience, as space at the restaurant is limited.

 

Lectures:

Elia Fusi (University of Turin -  Italy)

Title: A first introduction to K-stability

Abstract: The aim of this lecture is to describe the main ideas and ingredients behind K-stability. In order to achieve that,  in the first part, I will discuss some famous results in GIT, such as the Hilbert-Mumford criterion and the Kempf-Ness' Theorem. With them serving as guidelines, I will move to discuss the moment map interpretation of the scalar curvature in Kähler geometry, due to Donaldson and Fujiki.  Finally,  I will focus on introducing the concept of K-stability, ultimately, stating the Yau-Tian-Donaldson conjecture and the known results concerning its validity.

Title: Equivariant volumes from localization in supergravity

Abstract: In this talk, I will review how the equivariant volume functional can be computed with localization techniques, such as the Duistermaat–Heckman formula and the theorem of Goertsches–Nozawa–Toeben, and I will explain how this volume functional enters in various extremization problems in supergravity that are relevant for holography. I will then focus on the localization of the on-shell action of D=5 gauged supergravity, and showcase how the equivariant volume appears from the computation.
