Let T be the complex projective torus, and X the surface CP Ã— T . Let XGal be its Galois cover with respect to a generic projection to CP . In this paper we compute the fundamental group of XGal ,â€¦ (More)

In this article, we compute the braid monodromy of two algebraic curves defined over R. These two curves are of complex level not bigger than 6, and they are unions of lines and conics. We use twoâ€¦ (More)

Computation of fundamental groups of Galois covers recently led to the construction and analysis of Coxeter covers of the symmetric groups [RTV]. In this paper we consider analog covers of Artinâ€™sâ€¦ (More)

Let T be a complex torus, and X the surface CP Ã—T . If T is embedded in CP then X may be embedded in CP . Let XGal be its Galois cover with respect to a generic projection to CP . In this paper weâ€¦ (More)

This is the final paper in a series of four, concerning the surface T Ã— T embedded in CP 8 , where T is a the one dimensional torus. In this paper we compute the fundamental group of the Galois coverâ€¦ (More)

Let C(T ) be a generalized Coxeter group, which has a natural map onto one of the classical Coxeter groups, either Bn or Dn. Let CY (T ) be a natural quotient of C(T ), and if C(T ) is simply-lacedâ€¦ (More)

This paper is the second in a series of three papers concerning the surface TÃ—T , where T is a complex torus. We compute the fundamental group of the branch curve of the surface in C, using the vanâ€¦ (More)

This is the first of a series of articles in which we shall study the fundamental groups of complements of some quadric-line arrangements. In contrast with the extensive literature on lineâ€¦ (More)
