vi invitiamo al seminario dei Baby Geometri di questa settimana:

Presso la Saletta Riunioni (Dipartimento di matematica)

(University of Glasgow)

terrà un seminario dal titolo:

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.

Tutte le persone interessate sono invitate a partecipare.

A presto,

Lə organizzatorə
