摘要：
A generalized canonical formulation of gravity is devised for foliations of spacetime with codimension n greater than or equal to 1. The new formalism retains n-dimensional covariance and is especially suited to 2 + 2 decompositions of spacetime. It is also possible to use the generalized formalism to obtain boundary contributions to the 3 + 1 Hamiltonian. [S0556-2821(97)03322-5].
