Abstract
Let π³, π΄, π΅ be real Hilbert spaces, let f : π³ β β βͺ {+β}, g : π΄ β β βͺ {+β} be closed convex functions and let A : π³ β π΅, B : π΄ β π΅ be linear continuous operators. Given a sequence (Ξ³ n ) which increases towards infinity as n β +β, we study the following alternating proximal algorithm:
