Schubert calculus, Virasoro constraints and vertex operators

2025-01-20

Speaker: Miguel Moreira (MIT, USA)

The Virasoro constraints are one of the major open problems in enumerative geometry, originally in Gromov-Witten theory, but more recently also for moduli spaces of sheaves or representations of quivers. The latter have connections to vertex algebras and wall-crossing. In this...

Uma pequena introdução aos Autómatos Topológicos

2025-02-04

Speaker: Diogo Abreu (CEMAT, Univ. Lisboa)

Uma ferramenta fundamental no estudo das linguagens racionais é a sua conexão com autómatos e monoides finitos. O sucesso dessa relação vem, sobretudo, do fato das estruturas envolvidas serem finitas. No entanto, ao tentarmos expandir esta teoria para linguagens mais gerais, como as...

Categorical programming with MATLAB and Octave: An analysis of built-in functions and coequalizer implementation

2025-02-04

Speaker: Nelson Martins-Ferreira (CDRSP, ESTG, IP Leiria)

In this talk, we will examine standard built-in functions of computer programming, such as unique, ismember, sortrows, sparse, and others, by extracting their categorical properties. We will introduce a procedure to implement a programming function called coeq, which exhibits categorical...
