Twist Positivity for Lagrangian Symmetries *
We prove twist positivity and positivity of the pair correlation function for combined spatial and internal symmetries of free bosonic Lagrangians. We work in a general setting, extending the results obtained in Twist Positivity [1]. Work supported in part by the Department of Energy under Grant DE-FG02-94ER-25228. This research was carried out in part for the Clay Mathematics Institute.

متن کاملTwist Positivity
We study a heat kernel e defined by a self-adjoint Hamiltonian H acting on a Hilbert space H, and a unitary representation U(g) of a symmetry group G of H, normalized so that the ground vector of H is invariant under U(g). The triple [H, U(g), H] defines a twisted partition function Zg and a twisted Gibbs expectation ( } ) g , Zg=TrH (U(g) e&;H) and ( } ) g=TrH (U(g) } e) TrH (U(g) e). We say t...
متن کاملThe Symmetries of Equivalent Lagrangian Systems and Constants of Motion
In this paper Mathematical structure of time-dependent Lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent Lagrangian systems are considered. Starting point is time-independent Lagrangian systems ,then we extend mathematical concepts of these systems such as equivalent lagrangian systems to th...
