Let $\mathcal{F}_h^i(k,n)$ be the $i$th ordered configuration space of all distinct points $H_1,\ldots,H_h$ in the Grassmannian $Gr(k,n)$ of $k$-dimensional subspaces of $\mc^n$, whose sum is a subspace of dimension $i$. We prove that $\mathcal{F}_h^

In this paper we study normal singularities of complex analytic surfaces. In particular, since a normal surface has only isolated singularities (see, e.g., [10]), we restrict our attention to germs (S, s) where S is a connected normal surface, s ∈

In this paper the authors study generic covers of C 2 branched over {x n +y m }=0 s.t. the total space is a normal analytic surface. They found a complete description of the monodromy of the cover in terms of the monodromy graphs and an almost comple

Let B n be the braid group on n strings and let Φn : B n → S n be the standard homomorphism of B n onto the group of permutations of the set }1,…,n}. In this paper the author calculates, using the Reidemeister-Schreier method, a presentation for
