On the singular braid monoid of an orientable surface
(American Mathematical Society, 2004)In this paper we show that the singular braid monoid of an orientable surface can be embedded in a group. The proof is purely topological, making no use of the monoid presentation.

On the ubiquity of trivial torsion on elliptic curves
(Springer, 2010-08)The purpose of this paper is to give a down-to-earth proof of the well–known fact that a randomly chosen elliptic curve over the rationals is most likely to have trivial torsion.

On the unit of a monoidal model category
(Elsevier, 2015-08-15)In this paper we show how to modify cofibrations in a monoidal model category so that the tensor unit becomes cofibrant ...

Ordering pure braid groups on compact, connected surfaces
(University of California, 2002-04)We prove that the pure braid groups on compact, connected, orientable surfaces are bi-orderable, and that the pure braid groups on compact, connected non-orientable surfaces have generalized torsion, thus they are not bi-orderable.

Polynomial braid combing
(Oxford University Press, 2018)We prove that, for n ≥ 3, the minimal dimension of a model of the classifying space of the braid group Bn, and of the pure braid group Pn, with respect to the family of virtually cyclic groups is n.
