Abstract

We complete the construction of the biassociahedra KKKK, construct the free matrad H\mathcal{H}_{\infty}, realize H\mathcal{H}_{\infty} as the cellular chains of KK,KK, and define an AA_{\infty}-bialgebra as an algebra over H.\mathcal{H}_{\infty}. We construct the bimultiplihedra JJ,JJ, construct the relative free matrad rHr\mathcal{H}_{\infty} as a H\mathcal{H}_{\infty}-bimodule, realize rHr\mathcal{H}_{\infty} as the cellular chains of JJJJ, and define a morphism of AA_{\infty}-bialgebras as a bimodule over H\mathcal{H}_{\infty}. We prove that the homology of every AA_{\infty}-bialgebra over a commutative ring with unity admits an induced AA_{\infty}-bialgebra structure. We extend the Bott-Samelson isomorphism to an isomorphism of AA_{\infty}-bialgebras and determine the AA_{\infty} -bialgebra structure of H(ΩΣX;Q)H_{\ast}\left( \Omega\Sigma X;\mathbb{Q}\right) . For each n2n\geq2, we construct a space XnX_{n} and identify an induced nontrivial AA_{\infty}-bialgebra operation ω2n:H(ΩXn;Z2)2H(ΩXn;Z2)n\omega_{2}^{n}: H^{\ast}\left(\Omega X_{n};\mathbb{Z}_{2}\right) ^{\otimes2}\rightarrow H^{\ast}\left(\Omega X_{n};\mathbb{Z}_{2}\right) ^{\otimes n}.
