Cohomology of the complement of a free divisor
(American Mathematical Society, 1996-08)We prove that if D is a "strongly quasihomogeneous" free divi- sor in the Stein manifold X, and U is its complement, ...

New presentations of surface braid groups
(World Scientific Publishing, 2001)In this paper we give new presentations of the braid groups and the pure braid groups of a closed surface. We also give an algorithm to solve the word problem in these groups, using the given presentations.

A computational approach to the D-module of meromorphic functions
(2001)Let D be a divisor in Cn. We present methods to compare the D-module of the meromorphic functions O[∗D] to some natural approximations. We show how the analytic case can be treated with computations in the Weyl algebra.

On the dimension of discrete valuations of k ((X1, ..., Xn))
(Elsevier, 2001-07-01)Let v be a rank-one discrete valuation of the field Kn=k((X1,…,Xn)). We know, after [1], that if n=2 then the dimension ...

The Kronecker product of Schur functions indexed by two-row shapes or hook shapes
(Springer, 2001-09)The Kronecker product of two Schur functions sµ and sν, denoted by sµ ∗ sν, is the Frobenius characteristic of the tensor ...
