Instituto Argentino de Matemática "Alberto P. Calderón"; Argentina. An idempotent operator E in a Hilbert space H(E2= 1) is written as a 2 × 2 matrix in terms of the orthogonal decomposition H=R(E)?R(E)?(R(E) is the range of E) as (Formula Presented). We study the sets of idempotents that one obtains when E1 , 2: R(E)?? R(E) is a special type of operator: compact, Fredholm and injective with dense range, among others. 2024-12-23T13:38:30Z 2024-12-23T13:38:30Z 2016 info:eu-repo/semantics/article info:ar-repo/semantics/artículo info:eu-repo/semantics/publishedVersion Andruchow, E.
