Abstract

Tutte's 3-flow conjecture asserts that every 4-edge-connected graph admits a nowhere-zero 3-flow. We prove that this conjecture is true for every Cayley graph of valency at least four on any supersolvable group with a noncyclic Sylow 2-subgroup and every Cayley graph of valency at least four on any group whose derived subgroup is of square-free order.

超可溶群上 Cayley 图中的无处零 3 流

Tutte 的 3 流猜想断言，每个 4 边连接图都有一个无处为零的 3 流。我们证明，对于任何具有非循环 Sylow 2 子群的可超溶群上每一个至少四价的 Cayley 图，以及任何派生子群为无平方阶的群上每一个至少四价的 Cayley 图，这一猜想都是真的。
