Abstract

SANCHEZ-GUEVARA, Jesús. E-infinity coalgebra structure on chain complexes with integer coefficients. Rev.colomb.mat. [online]. 2021, vol.55, n.2, pp.197-203. Epub May 31, 2022. ISSN 0034-7426. https://doi.org/10.15446/recolma.v55n2.102690.

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.
