摘要
We give here a partial solution to a problem of Monk ([2]). Let kappa be a regular cardinal and let {L(i) : i < kappa} be a family of linear orderings with first element such that no L(i) contains a strictly decreasing sequence of length kappa+. Then Ind(PI(i<kappa) Intalg(L(i))) less-than-or-equal-to 2kappa.
