Absolute continuity of spectral shift for functions of contractions, dissipative operators,
unitary operators and self-adjoint operators. To establish
A criterion for unitary congruence between complex matrices and R. A. Horn, we propose a criterion for verifying
unitary congruence of these matrices. The criterion
