Abstract
In this paper, a generic 2-generalized Bregman nonspreading mapping is introduced.
Also, a Halpern-type iterative scheme for the approximation of attractive point of
such mapping is constructed in the setting of Banach space. The result established
generalized some recently announced results in the literature.

1 Introduction
Let C be a nonempty subset of a real Hilbert space H and T : C → H be a nonlinear
map. A point x ∈ H is called an attractive point of T if ‖x − Ty ‖≤‖x − y ‖ for all
y ∈ C . Let the sets of attractive and fixed points of T be, respectively, denoted
by A(T ) and F (T ), i.e., A(T ) ={u ∈ H :‖T v − u ‖≤‖v − u ‖, ∀v ∈ C } and
F (T ) ={u ∈ C : Tu = u }. The concept of attractive point was first introduced in
Hilbert space by Takahashi and Takeuchi [31]. The introduction was motivated basi-
cally to get rid of the closedness and convexity hypotheses imposed on the nonempty
