Let T be a T-set, i.e., finite set of nonnegative integers satisfying 0 ? T,
and G graph. In the paper we study relations between T-edge spans
espT
(G) and espd?T
(G), where d is positive integer and
d ? = {0 ? t (max + 1): |t ? t/d T} .
We show that espd?T
(G) espT
(G) ? r, r 1, an
integer depends on G. Next focus case {0} and
show that
espd?{0}
(G) ?d(?c(G) 1)?,
where ?c(G) circular chromatic...
