Global results on CR submanifolds of Sasakian manifolds

2024-12-11

Speaker: Dario Di Pinto (CMUC, Univ. Coimbra)

In this talk I will introduce the notion of CR submanifolds of a Sasakian manifold, which is close to the classical concept of CR submanifold of a complex manifold, and it generalizes many definitions already known in literature. As consequence of the fact that CR submanifolds are naturally...

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...
