The existence of invariant approximations for R-subweakly commuting mappings is proved. Our results extend most of the known results to a new class of noncommuting mappings.

The aim of this note is to fill in a gap in our previous paper in this journal. Precisely, we give a new proof of the following theorem: let (0, A, +) be a \_-finite measure space with +(0)>0, 0<p<+ , and Y a separable subspace of a Banach space X. Then Y is proximinal in X iff L p (+, Y) is proximi
