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.
Keywords:
Hilbert space, remotest projections, greedy approximations, convergence rate.
