Partial Non-stationary Perturbation Determinants for a Class of ,-symmetric Operators,totic behavior of δ. (.) for . → ∞ and the spectral shift function for . and its diagonal part are studied. Analogous results for the case if the underlying space is a Hilbert space were obtained in .

Selfadjoint Extensions with Several Gaps: Finite Deficiency Indices,ir ., .} is monotone with respect to ., then for any self-adjoint operator . on some separable Hilbert space ℜ obeying dim(.(.)ℜ) ≤ .(.) there exists a self-adjoint extension . such that the spectral parts . and . are unitarily equivalent. The result generalizes a corresponding result of M.G. Krein for a single gap.
