摘要：

Attention is paid to the fact that in field theory a commutator of functional derivatives may differ from zero by surface integrals. Ashtekar's formalism is a primer which demonstrates that transformations looking locally canonical can lead to the appearance of surface terms in a symplectic form of field theory. The prescription for the delta-function is given that allows to preserve surface terms in local calculations of Poisson brackets.
