Cui Yun-an · Harbin Ligong Daxue xuebao · 2009
We first introduce a new metric between two bounded closed subsets of a Banach space and with this new metric we redefind the nonexpansive mapping,which we call M-nonexpansive mapping.It proved that in a reflexive Banach space with R(X)2 has the M fixed point property.
