Tetracomposition
L. Kluge, E. Paal
We consider basic algebraic constructions associated with an abstract pre-operad, such as a -algebra, total composition $\bul$, pre-coboundary operator $\de$, tribraces $\{…

Invitation to composition
L. Kluge, E. Paal, J. Stasheff
In 1963 [Ann. of Math. {\bf 78}, 267-288], Gerstenhaber invented a \emph{comp(osition)} calculus in the Hochschild complex of an associative algebra. In this paper, the first steps…
