局部共形辛流形上的含时哈密顿力学

Time-dependent Hamiltonian mechanics on a locally conformal symplectic manifold

Orlando Ragnisco, Cristina Sardon, Marcin Zając

摘要:

在本文中,我们的目的是提出一个简洁的,但也是全面的研究局部共形辛(lcs)流形上的含时(t依赖)的哈密顿动力学。我们提出了正则变换的广义几何理论,并在lcs流形上建立了含时的几何Hamilton-Jacobi理论。与以前的论文有关局部共形辛流形,在这里引入的时间依赖性带来了有趣的几何性质,因为它是介绍接触几何局部辛补丁。最后,我们展示了我们的形式主义的应用程序的例子,特别是,我们提出了系统的微分方程与时间相关的参数,其中承认不同的物理解释,我们将指出。

英文摘要:

In this paper we aim at presenting a concise but also comprehensive study of time-dependent (tdependent) Hamiltonian dynamics on a locally conformal symplectic (lcs) manifold. We present a generalized geometric theory of canonical transformations and formulate a time-dependent geometric Hamilton-Jacobi theory on lcs manifolds. In contrast to previous papers concerning locally conformal symplectic manifolds, here the introduction of the time dependency brings out interesting geometric properties, as it is the introduction of contact geometry in locally symplectic patches. To conclude, we show examples of the applications of our formalism, in particular, we present systems of differential equations with time-dependent parameters, which admit different physical interpretations as we shall point out.
