PreGarside monoids and groups, parabolicity, amalgamation, and FC property
We define the notion of preGarside group slightly lightening the definition of Garside group so that all Artin-Tits groups are preGarside groups. This paper intends to... -
FAST NIELSEN-THURSTON CLASSIFICATION OF BRAIDS
We prove the existence of an algorithm which solves the reducibility problem in braid groups and runs in quadratic time with respect to the braid length for any fixed... -
Convexity of parabolic subgroups in Artin groups
We prove that any standard parabolic subgroup of any Artin group is convex with respect to the standard generating set. -
Fixed points of endomorphisms and relations between metrics in preGarside mon...
Rodaro and Silva proved that the fixed points submonoid and the periodic points submonoid of a trace monoid endomorphism are always finitely generated. We show that...
