论文摘要
我们研究了单型仪条件的微小变化，我们称之为“衍生量规条件”。我们表明，在经典级别，这些条件完全等效到表面项。在量子水平上，可以通过类比与量规理论中的量规固定可以轻松实现衍生量规条件。这种情况可能在上下文中具有优势和缺点。
We study a slight variation of the unimodular gauge condition which we call "the derivative gauge condition". We show that at the classical level these conditions are completely equivalent up to a surface term. At the quantum level the derivative gauge condition can be easily implemented by analogy with gauge fixing in a quantum gauge theory. This condition might have advantages and disadvantages upon the context.
