Small Oriented Cycle Double Cover of Graphs
A small oriented cycle double cover (SOCDC) of a bridgeless graph G on n vertices is a collection of at most n - 1 directed cycles of the symmetric orientation, G s , of G such that each arc of G s lies in exactly one of the cycles. It is conjectured that every 2-connected graph except two complete...

Zusammenfassung: | A small oriented cycle double cover (SOCDC) of a bridgeless graph
G
on
n
vertices is a collection of at most
n
-
1
directed cycles of the symmetric orientation,
G
s
, of
G
such that each arc of
G
s
lies in exactly one of the cycles. It is conjectured that every 2-connected graph except two complete graphs
K
4
and
K
6
has an
SOCDC
. In this paper, we study graphs with
SOCDC
and obtain some properties of the minimal counterexample to this conjecture. |
