| 抄録: | The present note is a strengthening of a recent paper by K. Takazawa and Y. Yokoi (A generalized-polymatroid approach to disjoint common independent sets in two matroids, Discrete Mathematics (2019)). For given two matroids on E, under the same assumption in their paper to guarantee the existence of a partition of E into k common independent sets of the two matroids, we show that there exists a nearly uniform partition P of E into k common independent sets, where the difference of the cardinalities of any two sets in P is at most one. |
