E-infinity coalgebra structure on chain complexes with integer coefficients
E-infinito coalgebra estructura en complejos de cadenas con coeficientes enteros
1Universidad de Costa Rica, San José, Costa Rica
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.
Keywords: Operad theory; Chain complexes; E∞-coalgebras; 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.
Palabras clave: Teoría de operads; complejos de cadenas; E∞-coalgebras; operad de Barrat-Eccles
