Abstract
Let ,
,
be real Hilbert spaces, let
,
be two bounded linear operators. The multiple-set split equality common fixed-point problem (MSECFP) under consideration in this paper is to
(Section.Display)
where are integers,
and
are quasi-nonexpansive mappings with nonempty fixed-point sets. Note that, the above problem (1) allows asymmetric and partial relations between the variables
and
. If
and
, then the MSECFP (1) reduces to the multiple-set split common fixed-point problem proposed by Censor et al. In this paper, we introduce mixed cyclic and simultaneous iterative algorithms for the MSECFP (1). We introduce a way of selecting the stepsizes such that the implementation of our algorithms does not need any prior information about the operator norms. Weak convergence results are given.
