Characterization of regularity via variational stability of alternating projections sequences
Francesco Battistoni, Aris Daniilidis, Carlo Alberto De Bernardi +1
The notion of regular pair for two nonempty closed convex subsets and~ of a Hilbert space $\H$ was introduced by Borwein and Bauschke in 1993 to ensure convergence (…

A variational approach to the alternating projections method
Carlo A. De Bernardi, Enrico Miglierina
The 2-sets convex feasibility problem aims at finding a point in the nonempty intersection of two closed convex sets and in a Hilbert space . The method of alternating p…
