Abstract
In this article, we give a generalization of δ-twisted homology introduced by Jingyan Li, Vladimir Vershinin and Jie Wu, called Δ-twisted homology, which enriches the theory of δ-(co)homology introduced by Alexander Grigor’yan, Yuri Muranov and Shing-Tung Yau. We show that the Mayer—Vietoris sequence theorem holds for Δ-twisted homology. Applying the Δ-twisted ideas to Cartesian products, we introduce the notion of Δ-twisted Cartesian product on simplicial sets, which generalizes the classical work of Barratt, Gugenheim and Moore on twisted Cartesian products of simplicial sets. Under certain hypothesis, we show that the coordinate projection of Δ-twisted Cartesian product admits a fibre bundle structure.
