There is a generalisation of Thompson's groups constructed f rom the Thompson's group $V$ and Artin's braid group. The braided Thompson 's group $BV_2$ was independently introduced by Patrick Dehornoy and Matt hew G. Brin in 2006. In this talk we will explain how two extend this conc ept to a much bigger family of groups by using infinite braids: Infinitely braided Thompson's groups $BV_n(H)$\, where $H$ is a subgroup of the brai d group on $n$ strands. We will prove that they are indeed groups by using braided diagrams and rewriting systems. We will also see that they are fi nitely generated if $H$ is finitely generated and give an explicit set of generators for $BV_n(H)$ and some other cases. Slides will be in English a nd the talk will be given in Spanish.\n LOCATION:https://researchseminars.org/talk/SIMBa/2/ END:VEVENT END:VCALENDAR
