Basic zero-dimensional spaces: a unifying framework for continuity and openness
2025-10-21
Speaker: João Areias (DMUC)
The main goal of this talk is to extend results from point-free topology to more general settings. We start by studying how the notions of sublocale and localic map can be extended from locales (i.e. complete Heyting algebras) to Heyting semilattices. Motivated by the case of Heyting...

Dimension-free Fourier restriction inequalities
2025-10-24
Speaker: Diogo Oliveira e Silva (IST, Lisboa)
Let \( {{\bf R}_{\mathbb S^{d-1}}}(p\to q) \) denote the best constant for the \( L^p(\mathbb R^d)\to L^q(\mathbb S^{d-1}) \) Fourier restriction inequality to the unit sphere \( \mathbb S^{d-1} \), and let \( {\bf R}_{\mathbb S^{d-1}} (p\to q;\textup{rad}) \) denote the corresponding...

Special Colloquium on Fraudulent Publishing in Mathematical Sciences moderated by Jorge Buescu (EMS Vice-President, University of Lisbon, Portugal) Abstract: In November 2023, Clarivate Plc announced that it had excluded the entire field of mathematics from the most recent edition of its...

Terminal coalgebras in graduated categories
2025-11-20
Speaker: Jirí Adámek (Czech Technical Univ., Prague, Czech Republic)
Graduated categories were introduced in [1] in order to prove that finitary endofunctors are right adjoints iff they preserve countable limits. Recently, these categories turned out to be useful in categorical colagebra: every finitary endofunctor preserving finite intersections has a...
