标题： Gauge Theory by canonical Transformations

摘要： 电磁学、强相互作用和弱相互作用通常在拉格朗日描述中被表述为规范理论。 在本文中，我们提出了一种在明显协变的哈密顿形式主义中对U(1)规范理论的替代形式推导。 我们使用规范变换作为指导工具来形式化规范过程。 规范场的引入、其变换行为以及动态规范场拉格朗日量/哈密顿量是这种形式主义不可避免的后果，而自由规范拉格朗日量/哈密顿量的形式取决于规范共轭规范场的规范依赖性的选择。 显示英文摘要

摘要： Electromagnetism, the strong and the weak interaction are commonly formulated as gauge theories in a Lagrangian description. In this paper we present an alternative formal derivation of U(1)-gauge theory in a manifestly covariant Hamilton formalism. We make use of canonical transformations as our guiding tool to formalize the gauging procedure. The introduction of the gauge field, its transformation behaviour and a dynamical gauge field Lagrangian/Hamiltonian are unavoidable consequences of this formalism, whereas the form of the free gauge Lagrangian/Hamiltonian depends on the selection of the gauge dependence of the canonically conjugate gauge fields.
