Up to now there is no homotopy for Marcus-Wyse (for short M-) topological
spaces. In relation to the development of a homotopy for the category of
Marcus-Wyse (for short M-) topological spaces on Z2, we need to generalize
the M-topology on Z2 to higher dimensional spaces X ? Zn, n ? 3 [18]. Hence
the present paper establishes a new topology on Zn; n 2 N, where N is the set
of natural numbers. It is called the generalized Marcus-Wyse (for short H-)
topology and is denoted by (Zn, n). Besides, we prove that (Z3, 3) induces
only 6- or 18-adjacency relations. Namely, (Z3, 3) does not support a
26-adjacency, which is quite different from the Khalimsky topology for 3D
digital spaces. After developing an H-adjacency induced by the connectedness
of (Zn; n), the present paper establishes topological graphs based on the
H-topology, which is called an HA-space, so that we can establish a category
of HA-spaces. By using the H-adjacency, we propose an H-topological graph
homomorphism (for short HA-map) and an HA-isomorphism. Besides, we prove
that an HA-map (resp. an HA-isomorphism) is broader than an H-continuous map
(resp. an Hhomeomorphism) and is an H-connectedness preserving map. Finally,
after investigating some properties of an HA-isomorphism, we propose both an
HA-retract and an extension problem of an HA-map for studying HA-spaces.
