When are exact categories co-exact?
2025-10-07
Speaker: James Gray (Stellenbosch Univ., South Africa)
The aim of the talk is two-fold:
(i) to explain that finitely co-complete pretoposes are co-ideally-exact [J] and co-arithmetical [P], and (ii) to explain that there are conditions in common between additive and lextensive categories, which together with exactness (and finite...
Noncommutative Poisson structure and invariants of matrices
2025-10-07
Speaker: Xabier García-Martínez (Univ. de Santiago de Compostela, Spain)
In this talk we will explain how we used methods coming from non-associative algebras and from computational algebra to obtain the full description of the ring of invariants of pairs of \( 4\times 4 \) matrices, which could not be solved using the standard representation theory methods....

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...
