We determine the equilibria of a rigid loop in the plane, subject to the constraints of fixed length and fixed enclosed area. Rigidity is characterized by an energy functional quadratic in theâ€¦ (More)

We consider the motion of a particle described by an action that is a functional of the Frenet-Serret [FS] curvatures associated with the embedding of its worldline in Minkowski space. We develop aâ€¦ (More)

Several years ago, Linde and Vilenkin pointed out the possibility that the core of a localized topological defect could inflate under appropriate conditions in a process that was aptly dubbedâ€¦ (More)

Beginning from an effective theory in eight dimensions, in Ref.[1], Macias, Camacho and Matos proposed an effective model for the elec-troweak part of the Standard Model of particles in curvedâ€¦ (More)
