Hariz Bekkar Lourabi, Abdelouahab Mansour · Korean Journal of Mathematics · 2019
The aim of this paper is to present some necessary and sufficient conditions for existence of solution of Sylvester operator equation involving bounded subnormal operators in a Hilbert space. Our results improve and generalize some results in the literature involving normal operators.
