Abstract

Sullivan associated a uniquely determined D G A | Q to any simply connected simplicial complex E . This algebra (called minimal model) contains the total (and exactly) rational homotopy information of the space E . In case E is the total space of a principal G -bundle, ( G is a compact connected Lie-group) we associate a G -equivariant model U G [ E ] , which is a collection of “ G -homotopic” D G A ’s | R with G -action. U G [ E ] will, in general, be different from the Sullivan’s minimal model of the space E . U G [ E ] contains the total rational homotopy information of the spaces E , E / G and, in addition, it incorporates the action of G (on E ).

This algebra (called minimal model) contains the total (and exactly) rational homotopy information of the space $E$. In case $E$ is the total space of a principal $G$-bundle, ($G$ is a compact connected Lie-group) we associate a $G$-equivariant model $U_G[E]$, which is a collection of “$G$-homotopic” $DGA$’s$\big |_{\bf R}$ with $G$-action. $U_G[E]$ will, in general, be different from the Sullivan’s minimal model of the space $E$. $U_G[E]$ contains the total rational homotopy information of the spaces $E$, $E/G$ and, in addition, it incorporates the action of $G$ (on $E$).
