圈双覆盖猜想的构造性证明

A Constructive Proof of the Cycle Double Cover Conjecture

Alexander Souza

摘要:

圈双覆盖猜想指出,一个图是无桥的当且仅当存在一族边单圈,使得每条边恰好包含在其中的两个圈中。它是由Szekeres(1973)和Seymour(1979)独立提出的。本文对这一猜想作了肯定的回答。特别地,我们给出了一个在多项式时间内归纳地构造一个循环双重覆盖的算法。

英文摘要:

The cycle double cover conjecture states that a graph is bridge-free if and only if there is a family of edge-simple cycles such that each edge is contained in exactly two of them. It was formulated independently by Szekeres (1973) and Seymour (1979). In this paper, we settle the conjecture in the affirmative. In particular, we give an algorithm, which inductively constructs a cycle double cover in polynomial time.
