"An introduction to lattice gauge theories and equivalent models" by Malin Palö Forsström

Gauge theories are natural higher-dimensional generalizations of classical spin systems such as the Ising model, the Potts model, the XY model, and the Heisenberg model. As such, many classical tools for spin systems can be generalized to a framework that includes both gauge theories and classical spin systems. Using duality, these representations naturally lead to several other related models, each of which elucidates different properties of the original gauge theory. In this course, we will introduce gauge theories with and without external fields, describe several equivalent models, and show how these together explain some basic properties of gauge theories and other surface models in statistical mechanics.

Abstract 

This crash course offers a fast-paced introduction to some fundamental aspects of Dirichlet form theory, highlighting its role as a unifying framework for Markov processes, potential theory, and analysis on general state spaces. Beginning with symmetric bilinear forms on graphs, the course develops core concepts such as closability, regularity, and associated generators, and explains how Dirichlet forms encode diffusion, jump dynamics, and time changes. Time permitting, connections to analysis—particularly to conformal mappings—will also be discussed.

The FiRST Spring Meeting will take place in Vierumäki 5-6.3.2026. The meeting is targeted at members of the research groups of FiRST, and will include progress reports on all of the work packages, a poster session as well as social activities.

The Geometric and Probabilistic Aspects in Conformal Field Theory Programme, chaired by Associate Professor Eveliina Peltola, takes place at the Centre International de Rencontres Mathématiques (CIRM) in Marseille, France from July to December of 2026.

Research School - Loop Models, Conformal Field Theory, and Geometry

, taking place from the 24th to the 28th of August 2026, aims to introduce young researchers to the field of Loop Models, Conformal Field Theory and Geometry, and to enable established researchers to expand their scope and to interact with others having slightly different backgrounds but working on related problems.

Conference - Geometric and Probabilistic Aspects in Quantum Field Theory

Workshop - Logarithmic CFT, Loop Models, and Random Geometry

In the Logarithmic CFT, Loop Models, and Random Geometry Workshop, taking place 7-11.12.2026, the plan is to bring together experts with complementary expertise on these topics, for collaborating towards the rigorous foundations of CFT and especially their logarithmic aspects, and how they arise as scaling limits of lattice models.
