Abstract

The F\'elix-Tanr\'e rational model for the polyhedral product of a fibre inclusion is considered. In particular, we investigate the rational model for the polyhedral product of a pair of Lie groups corresponding to arbitrary simplicial complex and the rational homotopy group of the polyhedral product. Furthermore, it is proved that for a partial quotient NN associated with a toric manifold MM, the following conditions are equivalent: (i) N=MN=M. (ii) The odd-degree rational cohomology of NN is trivial. (iii) The torus bundle map from NN to the Davis-Januszkiewicz space is formalizable.
