Topological approach to phase transitions and inequivalence of statistical ensembles
Michael Kastner
The relation between thermodynamic phase transitions in classical systems and topology changes in their state space is discussed for systems in which equivalence of statistical ens…
The 3-cuspidal quartic and braid monodromy of degree 4 coverings
Fabrizio Catanese, Bronislaw Wajnryb
We study the discriminant of a degree 4 extension given by a deformed bidouble cover, i.e., by equations z^2= u + a w, w^2= v + bz. We first show that the discriminant surface is a…
Vortex motion in a finite-size easy-plane ferromagnet and application to a nanodot
Denis D. Sheka, Juan P. Zagorodny, Jean-Guy Caputo +2
We study the motion of a non-planar vortex in a circular easy-plane ferromagnet, which imitates a magnetic nanodot. Analysis was done using numerical simulations and a new collecti…
The moduli space of surfaces with
Ingrid C. Bauer, Fabrizio M. E. Catanese, Roberto Pignatelli
In this paper we answer a question posed by Horikawa in 1978, who showed that the above moduli space is composed of 11 locally closed strata building up 4 irreducible components an…
Beauville surfaces without real structures, I
Ingrid Bauer, Fabrizio Catanese, Fritz Grunewald
Inspired by a construction by Arnaud Beauville of a surface of general type with , the second author defined the Beauville surfaces as the surfaces which are rigid…
Threefolds with big and nef anticanonical bundles I
Priska Jahnke, Thomas Peternell, Ivo Radloff
We start the classification of smooth projective threefolds X whose anticanonical bundles -K_X are big and nef but not ample. In this paper we treat the case b_2(X) = 2 and the mor…
