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...

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...
