AbstractThis paper compares three different methods of computing joint terms in the on-shell action of gravity, which are identifying the joint term by the variational principle in the Dirichlet boundary condition, treating the joint term as the limit contribution of a smooth boundary and finding the joint term by local SO(1, d - 1) transformation. In general metric gravitational theory, we show that the differences between these joint terms are variational invariants under a fixed boundary condition. We also give an explicit condition to judge the existence of a joint term determined by the variational principle and apply it to general relativity as an example.
