%0 Journal Article %T Examples of Rational Toral Rank Complex %A Toshihiro Yamaguchi %J International Journal of Mathematics and Mathematical Sciences %D 2012 %I Hindawi Publishing Corporation %R 10.1155/2012/867247 %X There is a CW complex (), which gives a rational homotopical classification of almost free toral actions on spaces in the rational homotopy type of X associated with rational toral ranks and also presents certain relations in them. We call it the rational toral rank complex of X. It represents a variety of toral actions. In this note, we will give effective 2-dimensional examples of it when X is a finite product of odd spheres. This is a combinatorial approach in rational homotopy theory. %U http://www.hindawi.com/journals/ijmms/2012/867247/
