Nonisospectral flows on semiinfinite unitary block Jacobi matrices

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is proved that if the spectrum and spectral measure of a unitary operator generated by a semiinfinite block Jacobi matrix $J(t)$ vary appropriately, then the corresponding operator $\textbf{J}(t)$ satisfies the g...
