Abstract

Let C be a subset of a real Hilbert space H. Let T : H ! H be a strictly
k-pseudononspreading mapping with a nonempty xed point set. Let ! 2 [k; 1) be xed.
Let fT
i
g
N
i=1
be N k
-strictly pseudononspreading mappings. In this paper, we study the
relationship between of a xed point set of a k-strictly pseudononspreading mapping and
other forms of certain combinations of some k-strictly pseudononspreading mappings in
Hilbert space.
