Normal generation of line bundles on a general k -gonal algebraic curve

Edoardo Ballico, Changho Keem, Seonja Kim (2003)

Bollettino dell'Unione Matematica Italiana

We prove that a very ample special line bundle L of degree d > 3 g - 1 / 2 on a general k -gonal curve is normally generated if the degree of the base locus of its dual bundle K L - 1 does not exceed c k - 2 / 2 , where c := d - 3 g - 1 / 2 .

Normal surface singularities admitting contracting automorphisms

Charles Favre, Matteo Ruggiero (2014)

Annales de la faculté des sciences de Toulouse Mathématiques

We show that a complex normal surface singularity admitting a contracting automorphism is necessarily quasihomogeneous. We also describe the geometry of a compact complex surface arising as the orbit space of such a contracting automorphism.

Normality and non-normality of group compactifications in simple projective spaces

Paolo Bravi, Jacopo Gandini, Andrea Maffei, Alessandro Ruzzi (2011)

Annales de l’institut Fourier

Given an irreducible representation V of a complex simply connected semisimple algebraic group G we consider the closure X of the image of G in ( End ( V ) ) . We determine for which V the variety X is normal and for which V is smooth.

Normes p -adiques et extensions quadratiques

Christophe Cornut (2009)

Annales de l’institut Fourier

On classifie les orbites de H sur l’immeuble de Bruhat-Tits de G pour trois paires sphériques ( G , H ) de groupes p -adiques classiques.
