Loop Groups and Holomorphic Bundles

This paper considers the links between the geometry of the various flag manifolds of loop groups and bundles over families of rational curves. Aa an application, a stability result for the moduli on a rational ruled surface of G-bundles with additional flag structure along a line is proven for any reductive group; this gives the corresponding stability statement for any compact group K for the ...

Complex Hyperbolic Manifolds Homotopy Equivalent to a Riemann Surface

We construct actions of fundamental groups of Riemann surfaces by automorphisms of the complex hyperbolic plane, which realize all possible values of Toledo's invariant. For integer values of these actions are discrete embeddings. The quotient complex hyperbolic surfaces are disc bundles over Riemann surfaces, whose topological type is determined in terms of .

Automorphisms of K 3 Surfaces

In this note, we report some progress we made recently on the automorphisms groups of K3 surfaces. A short and straightforward proof of the impossibility of Z/(60) acting purely non-symplectically on a K3 surface, is also given, by using Lef-schetz fixed point formula for vector bundles.

Moduli Spaces of Vector Bundles over a Klein Surface

A compact topological surface S, possibly non-orientable and with non-empty boundary, always admits a Klein surface structure (an atlas whose transition maps are dianalytic). Its complex cover is, by definition, a compact Riemann surface M endowed with an anti-holomorphic involution which determines topologically the original surface S. In this paper, we compare dianalytic vector bundles over S...

Nevus Lipomatosus Cutaneous Superficialis: A Rare Case Report

Nevus lipomatosus cutaneous superficialis is a rare idiopathic hamartomatous anomaly of the skin characterized by the presence of clusters of mature fat cells among the collagen bundles of the dermis. The classic, or solitary type, presents with asymptomatic soft, skin-colored to yellow papules or nodules. We report the case of a 12-year-old boy with congenital, classical nevus lipomatosus cuta...
