Algebraic topology seeks to classify and analyse spaces by translating geometric and continuous properties into algebraic invariants. Among these, the fundamental group stands as a primary tool: it ...

Zeta functions serve as a powerful analytic tool to capture the distribution of algebraic substructures, generalising the classical Riemann and Dedekind frameworks to settings such as groups, rings ...

Inside the symmetries of a crystal shape, a postdoctoral researcher has unearthed a counterexample to a basic conjecture about multiplicative inverses. “I’m nearly at the end of the talk, and it’s ...
