The Global Dimension of ω-Smash Coproducts
L. Yu. Zhang, W. Pan Nanjing Agricultural University
Abstract:
We mainly study the global dimension of ω-smash coproducts. We show that if H is a Hopf algebra with a bijective antipode SH, and Cω⋈H denotes the ω-smash coproduct, then gl.dim(Cω⋈H)≤gl.dim(C)+gl.dim(H), where gl.dim(H) denotes the global dimension of H as a coalgebra.
Keywords:
spectral sequence, global dimension, ω-smash coproduct.
