The aim of this paper is to construct an E∞-operad inducing an E∞-coalgebra structure on chain complexes with integer coefficients, which is an alternative description to the E∞-coalgebra by the Barrat-Eccles operad.
El objetivo de este artículo es construir un E∞-operad que induce una estructura de E∞-coalgebra en los complejos de cadenas con coeficientes enteros. Esta construcción produce una descripción alternativa a la E∞-coalgebra del operad de Barrat-Eccles.
