The existence of an interpolating master action does not guarantee the same spectrum for the interpolated dual theories. In the specific case of a generalized self-dual (GSD) model defined as the addition of the Maxwell ...

Strong similarities have been long observed between the Galois (Categories Galoisiennes) and the Tannaka (Categories Tannakiennes) theories of representation of groups. In this paper we construct an explicit (neutral) ...

Estudiamos el concepto de distancia entre distribuciones de probabilidad y sus aplicaciones en problemas relevantes de la Física y la Biología. El eje central de este trabajo de tesis lo constituye la divergencia de ...

We argue that the distinction between framework and interaction theories should be taken carefully into consideration when dealing with the philosophical implications of fundamental theories in physics. In particular, ...

We study a class of lattice field theories in two dimensions that includes gauge theories. We show that in these theories it is possible to implement a broader notion of local symmetry, based on semisimple Hopf algebras. ...

We analyze two abelian Higgs systems with nonstandard kinetic terms. First, we consider a model involving the Maxwell <br />term. For a particular choice of the nonstandard kinetics, we are able to obtain generalized ...

We solve a second-order elliptic equation with quasi-periodic boundary conditions defined on a honeycomb lattice that represents the arrangement of carbon atoms in graphene. Our results generalize those found by Kuchment ...
