%0 Journal Article %T The Rational Toomer Invariant and Certain Elliptic Spaces %A Gregory Lupton %J Mathematics %D 2003 %I arXiv %X We give an explicit formula for the rational category of an elliptic space whose minimal model has a homogeneous-length differential. We also show that for such a space, there are no gaps in the sequence of integers realized as the rational Toomer invariant of some cohomology class. With an additional hypothesis, we show a result from which we deduce the relation dim(H^*(X;Q)) >= 2 cat_0(X). %U http://arxiv.org/abs/math/0309392v1
