论文摘要
在古典场理论中，沿边界的时空歧管对应于将相应的田地空间（作为差分级的Fréchet歧管）的纤维产物与同型。我们在BV-BFV形式主义（Batalin-vilkovisky形式主义与切割）的几个例子中明确构建了这种同喻。
In classical field theory, gluing spacetime manifolds along boundary corresponds to taking a fiber product of the corresponding spaces of fields (as differential graded Fréchet manifolds) up to homotopy. We construct this homotopy explicitly in several examples in the setting of BV-BFV formalism (Batalin--Vilkovisky formalism with cutting--gluing).
