WebApr 5, 2024 · Abstract. In this paper, we will introduce two new classes of generalized Drazin invertible operators on Hilbert space, which are called core–EP star and star core–EP operators, using the core–EP inverse and the adjoint of a given operator. We also represent here a few characterizations of these new operators from two points of view ... WebThe connection between the Riemann–Hilbert factorization on self-intersecting contours and a class of singular integral equations is studied with a pair of decomposing algebras.
