Linkage on arithmetically Cohen-Macaulay schemes with application to the classification of curves of maximal genus
Rita Ferraro
In this paper the author provides a generalization of classical linkage, i.e. linkage by a complete intersection of dim. 0 or 1 on arithmetically Cohen-Macaulay schemes of any dime…
Combinatorial properties of stable spin curves
Lucia Caporaso, Cinzia Casagrande
The geometry of the moduli space of stable spin curves is studied, with emphasis on its combinatorial properties. In this context, the standard graph theoretic framework is not jus…
Curves of genus g on an abelian variety of dimension g
Herbert Lange, Edoardo Sernesi
In this paper we prove a general theorem concerning the number of translation classes of curves of genus belonging to a fixed cohomology class in a polarized abelian variety of…
Drift in phase space: a new variational mechanism with optimal diffusion time
Massimiliano Berti, Luca Biasco, Philippe Bolle
We consider non-isochronous, nearly integrable, a-priori unstable Hamiltonian systems with a (trigonometric polynomial) -perturbation which does not preserve the unperturbed…
