弯曲背景下规范场的Poincare Cartan形式

Poincare Cartan Form for Gauge Fields in Curved Background

Pankaj Sharan

摘要:

将扩展相空间中的直接哈密顿场论应用于弯曲时空背景下的规范场。这些场是微分1-形式,具有2-形式的正则动量。物质场和规范场的Poincare-Cartan 4-形式必须用协变导数代替外导数以保持规范不变性。

英文摘要:

The `directly Hamiltonian' field theory in the extended phase space is applied to gauge fields in curved spacetime background. These fields being differential 1-forms, have canonical momenta which are 2-forms. The Poincare-Cartan 4-forms for matter and gauge fields have to be modified with the exterior derivatives replaced by the covariant derivative for maintaining gauge invariance.
