Superficies isoperimétricas estables en Kerr y flujo de curvatura media
(2014-09-12)
Se estudia la evolución de hipersuperficies en datos iniciales de la ecuación de Einstein. Por medio de una ecuación de flujo que involucra principalmente la curvatura media de la hipersuperficie. Se obtiene la evolución ...
Compactly-supported and relative integration in differential cohomology
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2022-04-11)
In this work, we have constructed more general versions of differential integration maps
in differential cohomology theories. Among the obtained versions we can mention the
integration with compact supports, the integration ...
Simetrías ocultas, twistors, y estabilidad de campos lineales en agujeros negros
(2018-05)
En el marco del problema de estabilidad de agujeros negros, esta tesis trata diversos aspectos de las ecuaciones de campos libres sin masa sobre espacio-tiempos curvos, con énfasis en espacios algebraicamente especiales ...

DGLA Dg and BV formalism
(Springer, 2020-12-11)
Differrential Graded Lie Algebra Dg was previously introduced in the context of current algebras. We show that under some conditions, the problem of constructing equivariantly closed form from closed invariant form is ...
Exotic dark spinor fields
(Springer, 2011-04-01)
Exotic dark spinor fields are introduced and investigated in the context of inequivalent spin structures on arbitrary curved spacetimes, which induces an additional term on the associated Dirac operator, related to a Cech ...
