THE
-LABELLING OF
Ping An (P. R. China), Yinglie Jin (P. R. China) and Mitsuo Kanemitsu (Japan)

is the set of nonzero zero-divisors.
Let
be a simple nonzero zero-divisor
graph with vertices
and for distinct
the vertices x
and y are adjacent if and only if
In this paper, we give the exact
value of l-number
of
with maximum degree D and minimum number
in the prime factorization of N,
and obtain an
-labelling algorithm of
