| Abstract: | Using a geometric approach (in particular, angles between subspaces), we establish useful estimates regarding convergence of infinite products involving orthogonal projections and other (possibly nonlinear) nonexpansive operators in Hilbert space. |
| Keywords: | Fixed point Hilbert space Infinite product Nonexpansive operator Orthogonal projection |
