On Superconductors and Torsion Vortices [PDF]

arXiv, 1998
The Meissner effect for superconductors in spacetimes with torsion is revisited.Two new physical interpretaions are presented.The first considers the Landau-Ginzburg theory yields a new symmetry-breaking vacuum depending on torsion.In the second interpretation a gravitational Meissner torsional effect where when the Higgs field vanishes, torsion and ...

A characterization of 2-fold torsion classes induced by $τ$-rigid modules [PDF]

arXiv
We introduce $n$-fold torsion(-free) classes of an abelian category. These are a generalization of ordinary torsion(-free) classes in the sense that $1$-fold torsion(-free) classes coincide with torsion(-free) classes. In the category of finitely generated modules over a finite dimensional algebra, we can naturally construct $n$-fold torsion classes ...

Gravitational Stability of inflaton and torsion in Einstein-Cartan-Klein-Gordon cosmology with kinky potentials [PDF]

arXiv, 2002
Gravitational stability of torsion and inflaton field in a four-dimensional spacetime de Sitter solution in scalar-tensor cosmology where Cartan torsion propagates is investigated in detail. Inflaton and torsion evolution equations are derived by making use of a Lagrangean method.

Cappell-Miller analytic torsion for manifolds with boundary [PDF]

arXiv, 2009
Inspired by the work of Boris Vertman on refined analytic torsion for manifolds with boundary, in this paper we extend the construction of the Cappell-Miller analytic torsion to manifolds with boundary. We also compare it with the refined analytic torsion on manifolds with boundary.

A 2-dimensional torsion theory on symmetric monoidal categories [PDF]

arXiv
In this paper we describe a homotopy torsion theory in the category of small symmetric monoidal categories. Thanks to the use of natural isomorphisms as basis for the nullhomotopy structure, this homotopy torsion theory enjoys some interesting 2-dimensional properties which may be the starting point for a definition of "2-dimensional torsion theory ...

Reidemeister torsion and analytic torsion of spheres [PDF]

arXiv, 2009
We provide a simple topological derivation of a formula for the Reidemeister and the analityc torsion of spheres.
