Higher-order systems Lagrangian and Hamiltonian formalisms Symplectic and presymplectic manifolds
2011/7/26
Abstract: The Lagrangian-Hamiltonian unified formalism of R. Skinner and R. Rusk was originally stated for autonomous dynamical systems in classical mechanics. It has been generalized for non-autonomo...

A New Proposal for the Picture Changing Operators in the Minimal Pure Spinor Formalism
New Proposal the Minimal Pure Spinor Formalism High Energy Physics - Theory
2011/7/27
Abstract: Using a new proposal for the "picture lowering" operators, we compute the tree level scattering amplitude in the minimal pure spinor formalism by performing the integration over the pure spi...
We use the supergeometric formalism, more precisely, the so-called “big bracket”(for which brackets and anchors are encoded by functions on some graded symplectic manifold) to address the theory of Ja...
The goal of this paper is to present a formalism that allows to handle fourfermion effective theories at finite temperature and density in curved space. The formalism is based on the use of the effect...
