The biderivative and $A\sb \infty$-bialgebras

Abstract

An $A_{\infty }$-bialgebra is a DGM $H$ equipped with structurally compatible operations $\left\{ \omega ^{j,i}:H^{\otimes i}\rightarrow H^{\otimes j}\right\}$ such that $\left( H,\omega ^{1,i}\right)$ is an $% A_{\infty }$-algebra and $\left( H,\omega ^{j,1}\right)$ is an $A_{\infty }$% -coalgebra. Structural compatibility is controlled by the biderivative operator $Bd$, defined in terms of two kinds of cup products on certain cochain algebras of pemutahedra over the universal PROP $U=End\left(TH\right)$.
