摘要: 研究了均匀拟阵二阶圈图在某些条件下的哈密顿性。从U2,n,U3,n 的二阶圈图在某些条件下的哈密顿性,推广到Um,n 的二阶圈图在某些条件下的哈密顿性。发现当n = m + 2,m + 3,?,2m 时,Um,n 的二阶圈图是哈密顿连通的并且是一致哈密顿的,其中m,n 均为正整数,且m ≥ 2,n ≥ m + 2。

关键词: 均匀拟阵, 拟阵的圈图, 哈密顿连通, 一致哈密顿

Abstract: Hamilton properties of second-order cyclic graphs of uniform matroid under certain conditions were studied. From Hamilton properties of second-order cyclic graphs of U2,n and U3,n under certain conditions,generalizing to Hamilton properties of second-order cyclic graphs of Um,n under certain conditions. We discovered second-order cyclic graphs of Um,n was Hamiltonian-connected and uniformly Hamilton,if n = m + 2,m + 3,?,2m,m,n were positive integer and m ≥ 2,n ≥ m + 2.

Key words: uniform matroid, cyclic graph of matroids, Hamiltonian-connected, uniformly Hamilton
