Also, the vorticity (the physical concept that measures the "swirl" or "curl" in a fluid motion) because of the earth's rotation is very large compared with the vorticity of typical motions that occur on a large scale in the ocean or atmosphere. It is frequently convenient in the study ...
Multiparticle SYM equations of motion and pure spinor BRST blocks In this paper a multiparticle generalization of linearized ten-dimensional super Yang-Mills superfields is proposed. Their equations of motions are shown t... CR Mafra,O Schlotterer - 《Journal of High Energy Physics》 被引量: ...
Equations of motion for single particle under two proper time model and three proper time model have been proposed and analyzed. The motions of particle are derived from pure classical method but they exhibit the same properties of quantum physics: the quantum wave equation, de Broglie equations,...
Quantum field theories based on interactions which contain the Moyal star product suffer, in the general case when time does not commute with space, from several diseases: quantum equation of motions contain unusual terms, conserved currents cannot be defined and the residual spacetime symmetry is no...
A perturbation approach is presented in which the quantities defining the rigid-body maneuver are regarded as the unperturbed motion and the elastic motions and deviations from the rigid-body motions are regarded as the perturbed motion. The perturbation equations are linear, non-self-adjoint, and ...
Then, the equations for the rigid-body motions are transformed into a symbolic vector form of Lagrange’s equations in terms of general quasi-coordinates. The hybrid Lagrange’s equations of motion in terms of general quasi-coordinates are subsequently expressed in terms of quasi-coordinates ...
This paper is concerned with the general motion of a flexible body in space. Using the extended Hamilton's principle for distributed systems, standard Lagrange's equations for hybrid systems are first derived. Then, the equations for the rigid-body motions are transformed into a symbolic vector ...
In particular, we will derive the solution for both bounded and unbounded motions. On the other hand, through a direct approach, we will be able to handle the 位 < 0 case as well, getting an explicit formula for t = t(r) holding in the punctured open ball 0 < r < rs =. 1 , ...
