On the existence of solutions to the operator Riccati equation and the tanΘtheorem

Vadim Kostrykin, Konstantin A. Makarov, Alexander K. Motovilov

Let A and C be self-adjoint operators such that the spectrum of A lies in a gap of the spectrum of C and let d>0 be the distance between the spectra of A and C. We prove that under…
