چکیده

Let D and G be copies of the open unit disc in C, let A (resp. B) be a measurable subset of ∂D (resp. ∂G), let W be the 2-fold cross ( (D ∪A)×B ) ∪ ( A× (B ∪G) ) , and let M be a relatively closed subset of W. Suppose in addition that A and B are of positive one-dimensional Lebesgue measure and that M is fiberwise polar (resp. fiberwise discrete) and that M ∩(A×B) = ∅. We determine the “envelope of holomorphy” Ŵ \ M of W \ M in the sense that any function locally bounded on W \M, measurable on A×B, and separately holomorphic on ( (A × G) ∪ (D × B) ) \ M “extends” to a function holomorphic on Ŵ \ M.

1 1 M ay 2 00 4 Singularities of the Prym Theta Divisor

For the Jacobian of a curve, the Riemann singularity theorem gives a geometric interpretation of the singularities of the theta divisor in terms of special linear series on the curve. This paper proves an analogous theorem for Prym varieties. Applications of this theorem to cubic threefolds, and Prym varieties of dimension five, are also considered.

7 M ay 2 00 2 On the L 2 – Stokes theorem and Hodge theory for singular algebraic varieties

For a projective algebraic variety V with isolated singularities, endowed with a metric induced from an embedding, we consider the analysis of the natural partial differential operators on the regular part of V . We show that, in the complex case, the Laplacians of the de Rham and Dolbeault complexes are discrete operators except possibly in degrees n, n±1, where n is the complex dimension of V...

Abstract We study the boundary behaviour of solutions u of −∆Nu + |u| u = 0 in a bounded smooth domain Ω ⊂ R subject to the boundary condition u = 0 except at one point, in the range q > N − 1. We prove that if q ≥ 2N − 1 such a u is identically zero, while, if N − 1 < q < 2N − 1, u inherits a boundary behaviour which either corresponds to a weak singularity, or to a strong singularity. Such si...

1 M ay 2 00 9 ON THE BRIANÇON - SKODA THEOREM ON A SINGULAR VARIETY

Let Z be a germ of a reduced analytic space of pure dimension. We provide an analytic proof of the uniform BriançonSkoda theorem for the local ring OZ ; a result which was previously proved by Huneke by algebraic methods. For ideals with few generators we also get much sharper results.

2 8 M ay 2 00 1 Poisson cohomology in dimension two Philippe MONNIER

It is known that the computation of the Poisson cohomology is closely related to the classification of singularities of Poisson structures. In this paper, we will first look for the normal forms of germs at (0,0) of Poisson structures on K (K = R or C) and recall a result given by Arnold. Then we will compute locally the Poisson cohomology of a particular type of Poisson structure.
