Bethe-Salpeter bound-state structure in Minkowski space
(Elsevier B.V., 2016-08-10)
The quantitative investigation of the scalar Bethe-Salpeter equation in Minkowski space, within the ladder-approximation framework, is extended to include the excited states. This study has been carried out for an interacting ...
Radial solutions of quasilinear equations in Orlicz-Sobolev type spaces
(ElsevierSan Diego, 2015-08)
This paper is devoted to prove the existence of a nontrivial nonnegative radial solution for the quasilinear elliptic equation [...] The function ϕ is allowed to belong to a larger class, which includes the special cases ...

Transition amplitude for two-time physics
(AMER PHYSICAL SOC, 2010)
We present the transition amplitude for a particle moving in a space with two times and D space dimensions having an Sp(2, R) local symmetry and an SO(D, 2) rigid symmetry. It was obtained from the BRST-BFV quantization ...

Wave action limits crowding in an intertidal mussel
(Inter-Research, 2015-01)
Intraspecific competition for space is generally invoked as the chief process limiting crowding in sessile or highly sedentary marine invertebrates. However, the mechanisms by which high conspecific density induces individual ...
Wide vector solitons in systems with time- and space-modulated nonlinearities
(2013-11-08)
In this work we apply point canonical transformations to solve some classes of two coupled nonautonomous nonlinear Schrödinger equations with specific cubic and quintic - time- and space-dependent - nonlinearities. The ...
Discrete squeezed states for finite-dimensional spaces
(Amer Physical Soc, 2007-09-01)
We show how discrete squeezed states in an N-2-dimensional phase space can be properly constructed out of the finite-dimensional context. Such discrete extensions are then applied to the framework of quantum tomography and ...

Habitat heterogeneity and use of physical and acoustic space in anuran communities in Southeastern Brazil
(2008-12-29)
Habitat heterogeneity and use of physical and acoustic space in anuran communities in Southeastern Brazil. We intended to verify if structural and physiognomical characteristics of water bodies influence on the degree of ...
