For a contracting operator in a space with an indefinite metric (i.e., for a doublyJ-nonexpanding operator) a characteristic operator-function is defined. On the basis of a detailed investigation of the properties of regular dilatations and characteristic functions of doubly $J$-nonexpanding operato...
