Carə tuttə, vi invitiamo al seminario dei Baby Geometri di questa settimana: *Giovedì 23 Aprile 2026, alle ore 11:15* Presso la Saletta Riunioni (Dipartimento di matematica) *Susanna Terron* (University of Glasgow) terrà un seminario dal titolo: *Constructing Thompson representatives* di cui riportiamo l'abstract: In 2017 Vaughan Jones introduced a construction associating links to elements of Thompson’s group F. He then proved that all links can be obtained in such a way, opening the way to new possible connections between these objects. I will present Jones’ construction and extend it to obtain a surjective map into the set of pointed links. I’ll then define a new algebraic structure by endowing the group F3 with a monoid operation, which turns our map into a surjective monoid homomorphism. As a consequence, we obtain a standard form for connected sum representatives, which can then be extended to obtain representatives for a certain family of links, that we will refer to as tree links. Vi ricordiamo infine che potrete trovare informazioni sui prossimi seminari sul nostro sito <https://sites.google.com/view/babygeometri/home>. Tutte le persone interessate sono invitate a partecipare. A presto, Lə organizzatorə
