Action-angle representation of waves and instabilities in flowing plasmas
Action-angle representation of linear fluctuation in plasma is formally performed by taking the Lagrange-Hamilton theory as the basis and invoking the recent spectral technique [Hirota and Fukumoto, J. Math. Phys. 49 083101 (2008)], which is shown to be applicable equally to the magnetohydrodynamic (MHD) system and the Vlasov-Maxwell system. This formalism leads to a natural definition of the w...
متن کاملAction-Angle Variables for Complex Projective Space and Semiclassical Exactness
We construct the action-angle variables of a classical integrable model defined on complex projective phase space and calculate the quantum mechanical propagator in the coherent state path integral representation using the stationary phase approximation. We show that the resulting expression for the propagator coincides with the exact propagator which was obtained by solving the time-dependent ...
متن کاملAction Chart: A Representation for Efficient Recognition of Complex Activities
In this paper we propose an efficient method for the recognition of long and complex action streams. First, we design a new motion feature flow descriptor by composing low-level local features. Then a new data embedding method is developed in order to represent the motion flow as an one-dimensional sequence, whilst preserving useful motion information for recognition. Finally attentional motion...
متن کاملAction Chart: A Representation for Efficient Recognition of Complex Activity
Action recognition has been widely studied for decades and there are many successful approaches to recognize relatively simple actions [2]. Recently, more realistic and complex activity recognition tasks have been dealt with, but the current status of the research on complex activities is in its initial phase and far from the recognition ability of human. In our work, we are interested in recog...
متن کاملAn angle representation of QCD ∗
For the sake of eliminating gauge variant degrees of freedom we discuss the way to introduce angular variables in the hamiltonian formulation of QCD. On the basis of an analysis of Gauss’ law constraints a particular choice is made for the variable transformation from gauge fields to angular field variables. The resulting formulation is analogous to the one of Bars in terms of corner variables ...
