Definitizable operators in Krein spaces have spectral properties similar to those of selfadjoint operators in Hilbert spaces. A sufficient condition for definitizability of a selfadjoint operator A with a nonempty resolvent set ρ(A) in a Krein space (H,[·❘·]) is the finiteness of the number of negative squares of the form [Ax❘y] (see [10, p. 11]).
