Петр Анатольевич Бородин, L. Sh. Burusheva · Functional Analysis and Its Applications · 2023
Abstract We give an estimate of the rate of convergence to zero of the norms of remotest projections on three subspaces of a Hilbert space with zero intersection for starting vectors in the sum of orthogonal complements to these subspaces.
