Virulent strains of the coccidian parasiteToxoplasma gondii become attenuated so as to survive and complete their life cycle; however, it is not known whether the attenuation process is attributable to an innate cystogenic capacity of the parasite or to host-induced mechanisms. This report presents direct evidence of RH cystogenesis in non-immunised Fischer… (More)

We describe smooth projective horospherical varieties with Picard number 1. Moreover we prove that the automorphism group of any such variety acts with at most two orbits and we give a geometric characterisation of non-homogeneous ones.

We describe the Minimal Model Program in the family of Q-Gorenstein projective horo-spherical varieties, by studying a family of polytopes defined from the moment polytope of a Cartier divisor of the variety we begin with. In particular, we generalize the results on MMP in toric varieties due to M. Reid, and we complete the results on MMP in spherical… (More)

For a few pairs (G ⊂ ˆ G) of reductive groups, we study the decomposition of irreduciblê G-modules into G-modules. In particular, we observe the saturation property for all of these pairs.

We use the Grossberg-Karshon's degeneration of Bott-Samelson varieties to toric varieties and the description of cohomolgy of line bundles on toric varieties to deduce vanishing results for the cohomology of lines bundles on Bott-Samelson varieties.

We classify all smooth projective horospherical varieties with Picard number 1. We prove that the automorphism group of any such variety X acts with at most two orbits and that this group still acts with only two orbits on X blown up at the closed orbit. We characterize all smooth projective two-orbit varieties with Picard number 1 that satisfy this latter… (More)

Let X be a minuscule homogeneous space, an odd-dimensional quadric, or an adjoint homogenous space of type different from A and G 2. Le C be an elliptic curve. In this paper, we prove that for d large enough, the scheme of degree d morphisms from C to X is irreducible, giving an explicit lower bound for d which is optimal in many cases.

The authors report a case of urinary calculi secondary to glafenine which posed a difficult problem in the radiological diagnosis. They review the literature of iatrogenic urinary calculi and discuss the place of radiology (Excretory Urography, Ultrasound and Computed Tomography) in the diagnosis.

We prove a conjecture of L. Bonavero, C. Casagrande, O. Debarre and S. Druel, on the pseudo-index of smooth Fano varieties, in the special case of horospherical varieties. Let X be a normal, complex, projective algebraic variety of dimension d. Assume that X is Fano, namely the anticanonical divisor −K X is Cartier (in other words, X is Gorenstein) and… (More)
