Unrestricted iterations of relaxed projections in Hilbert space: Regularity, absolute convergence, and statistics of displacements

C. Sinan Güntürk, Nguyen T. Thao

Given a finite collection $\mathbf{V}:=(V_1,\dots ,V_N)$ of closed linear subspaces of a real Hilbert space $H$, let $P_i$ denote the orthogonal projection operator onto $V_i$ and $…
