An indefinite range inclusion theorem for triplets of bounded linear operators on a Hilbert space
Michio Seto, Atsushi Uchiyama
We study triplets of Hilbert space operators satisfying a certain inequality. A range inclusion theorem with norm estimate for those triplets is given with the language of Kre\uın…
