| 英文摘要 | Let M be a matroid on E boolean OR {1}, where 1 is not an element of E is a distinguished element of M. The l-port of M is the set P = {P: P subset of E with P boolean OR {1} a circuit of M}. Let A be the P-E incidence matrix. Let U(2,4) be the uniform matroid on four elements of rank two, let F(7) be the Fano matroid, let F*(7) be the dual of F(7), and let F(7)(+) be the unique series extension of F(7). In this paper, we prove that the system Ax >= 1, x >= 0 is box-totally dual integral (box-TDI) if and only if M has no U(2,4)-minor using 1, no F*(7)-minor using 1, and no F(7)(+)-minor using 1 as a series element. Our characterization yields a number of interesting results in combinatorial optimization. |
