Multiplicative tensors on Lie groupoids, and representations up to homotopy

2024-12-12

Speaker: João Nuno Mestre (CMUC, Univ. Coimbra)

We will describe a quasi-isomorphism between two cochain complexes: a recently introduced one computing the linear cohomology of the tensor products of vector bundles over groupoids, and the complex of an associated tensor product of representations up to homotopy. The construction is...

Modelling growing epithelial tissues: from nuclear crowding to tissue shape and cell extrusion

2024-12-13

Speaker: Marina Ferreira (CNRS & IMT, Univ. Toulouse, France)

Pseudostratified epithelial tissues are characterized by tightly packed cells with minimal intercellular space. The forces exerted between neighbouring cells play a crucial role on the tissue shape and dynamics. However, the precise effects of these contact forces remain poorly understood...

Definability and full abstraction for algebraic effects with recursion

2024-12-17

Speaker: Norihiro Yamada (CMUC, Univ. Coimbra)

In this talk, I present an overview of my recent work on an intersection between algebra, logic and topology: definability and full abstraction for algebraic theories in the sense of universal algebra combined with a well-known formal calculus for higher-order computation. The...

Limit-colimit pseudodistributive laws and associated pseudoalgebras

2024-12-17

Speaker: Rui Prezado (CIDMA, Univ. Aveiro)

The distributivity of limits over colimits is often a desirable trait for a category to possess. Included among the several examples of this behaviour, we find (infinitary) distributive categories, (infinitary) lextensive categories and (Grothendieck) toposes [2]. The theory of pseudomonads...
