v 1 1 9 A pr 1 99 4 VARIATIONAL FORMULATION OF LINEAR TIME - DEPENDENT INVARIANTS ∗
نویسندگان
چکیده
It is shown that linear time-dependent invariants for arbitrary multi-dimensional quadratic systems can be obtained from the Lagrangian and Hamil-tonian formulation procedures by considering a variation of coordinates and mo-menta that follows the classical trajectory and defines a noetherian symmetry transformation.

The time dependent-integrals of motion, linear in position and momentum operators, of a quantum system are extracted from Noether's theorem prescription by means of special time-dependent variations of coordinates. For the stationary case of the generalized two-dimensional harmonic oscillator, the time-independent integrals of motion are shown to correspond to special Bragg-type symmetry proper...

First order invariants of generic immersions of manifolds of dimension nm−1 into manifolds of dimension n(m+1)−1, m, n > 1 are constructed using the geometry of self-intersections. The range of one of these invariants is related to Bernoulli numbers. As by-products some geometrically defined invariants of regular homotopy are found.

This paper is a follow-up to [10], in which the author showed that the only real-valued finite type invariants of link homotopy are the linking numbers of the components. In this paper, we extend the methods used to show that the only real-valued finite type invariants of link concordance are, again, the linking numbers of the components.

The spin coherent state path integral describing the dynamics of a spin-12system in a magnetic field of arbitrary time-dependence is considered. Defining the path integral as the limit of a Wiener regularized expression, the semiclassical approximation leads to a continuous minimal action path with jumps at the endpoints. The resulting semiclassical propagator is shown to coincide with the exac...
