CHANGE LIFE: FROM URBAN REVOLUTION TO SPACE REVOLUTION - HENRI LEFEBVRE PROJECT
(Univ Federal Fluminense, 2018-05-01)
The Henri Lefebvre's theory of the production of space is nowadays one of the main debated contributions in contemporary social theory when the subject is the spatiality of social life. This paper has place in this discussion. ...
Symplectic Field Theories: Scalar and Spinor Representations
(Springer, 2018-03-01)
Using elements of symmetry, as gauge invariance, aspects of field theories represented in symplectic space are introduced and analyzed under physical bases. The states of a system are described by symplectic wave functions, ...
Characterization of coorbit spaces with phase-space covers
(Academic Press Inc Elsevier Science, 2012-01)
We show that coorbit spaces can be characterized in terms of arbitrary phase-space covers, which are families of phase-space multipliers associated with partitions of unity. This generalizes previously known results for ...
Perturbative symplectic field theory and Wigner function
(Elsevier, 2009-09-15)
We study relativistic quantum field theories in phase space, based on representations of the Poincaré group, using the Moyal product. We develop a perturbative theory for quantizing fields, with functional methods in phase ...
Examples of reflection positive field theories
(World Scientific, 2018-02)
The requirement of reflection positivity (RP) for Euclidean field theories is considered. This is done for the cases of a scalar field, a higher derivative scalar field theory and the scalar field theory defined on a ...
Stiefel and Grassmann manifolds in quantum chemistry
(Elsevier Science, 2012-08)
We establish geometric properties of Stiefel and Grassmann manifolds which arise in relation to Slater type variational spaces in many-particle Hartree-Fock theory and beyond. In particular, we prove that they are analytic ...
