Algebra, Geometry and Topology


Algebra, Geometry and Topology are very classical research areas in mathematics, sharing a long historical tradition of fruitful interactions among them. Since long ago, mainstream research in these areas has been present in Barcelona by several research groups, which cover a broad range of modern research lines, and mantain real connections and benefitial interactions among them.

The BGSMath currently has six research teams actively working in these three areas of mathematics, specifically covering the topics of commutative and non-commutative algebra, algebraic topology, algebraic and differential geometry, operator algebras, and geometric group theory.

Links to research groups

Researchers in the Barcelona area, and more generally in Catalonia, group themselves into smaller research groups, following not only academic but also administrative criteria, like location or research grants.
