Log-canonical forms and log canonical singularities

Hubert Flenner, Mikhail Zaidenberg

For a normal subvariety $V$ of $C^{n}$ with a good $C^{*}$ -action we give a simple characterization for when it has only log canonical, log terminal or rational singulariti…

Toric varieties whose blow-up at a point is Fano

Laurent Bonavero

We classify smooth toric Fano varieties of dimension $n \geq 3$ containing a toric divisor isomorphic to $\PP^{n-1}$. As a consequence of this classification, we show that any smoot…

Index Growth of hypersurfaces with constant mean curvature

Pierre Bérard, Levi Lopes de Lima, Wayne Rossman

In this paper we give the precise index growth for the embedded hypersurfaces of revolution with constant mean curvature (cmc) 1 in $R^{n}$ (Delaunay unduloids). When $n = 3$ , using…

Avoided crossings in mesoscopic systems: electron propagation on a non-uniform magnetic cylinder

Pavel Exner, Alain Joye

We consider an electron constrained to move on a surface with revolution symmetry in the presence of a constant magnetic field $B$ parallel to the surface axis. Depending on $B$ an…

Group completions via Hilbert schemes

Michel Brion

Let $X$ be a projective variety, homogeneous under a linear algebraic group. We show that the diagonal of $X$ belongs to a unique irreducible component $H_{X}$ of the Hilbert scheme…

Arakelov-type inequalities for Hodge bundles

Chris Peters

We give a proof of generalizations of the classical Arakelov inequality valid for the degree $d$ of the relative canoincal bundle of a family of curves of genus $g$ over a complete…
