Conjugacy in Garside Groups III: Periodic braids
(Elsevier, 2007-10-15)An element in Artin’s braid group Bn is said to be periodic if some power of it lies in the center of Bn. In this paper ...

Conjugacy problem for braid groups and Garside groups
(Elsevier, 2003-08-01)We present a new algorithm to solve the conjugacy problem in Artin braid groups, which is faster than the one presented ...

Conservation of the noetherianity by perfect transcendental field extensions
(European Mathematical Society, 2003)Let k be a perfect field of characteristic p>0, k(t)per the perfect closure of k(t) and A a k-algebra. We characterize whether the ring A⊗kk(t)per is noetherian when A is the ring of formal power series in n indeterminates over k.

Decomposing Jacobians of curves over finite fields in the absence of algebraic structure
(Elsevier, 2015-11)We consider the issue of when the L-polynomial of one curve over Fq divides the L-polynomial of another curve. We prove a ...
