Abstract
In this paper, we consider the split common null point problem in Banach spaces. Then using the idea of Mann's iteration, we prove a weak convergence theorem for finding a solution of the split common null point problem in Banach spaces. Furthermore, using the result, we get a new weak convergence theorem which is connected with the split common null point problem and an equilibrium problem in Banach spaces. It seems that these results are first in Banach spaces.
