The Bracket in the Bar Spectral Sequence for an Iterated Loop Space

Xianglong Ni

When $X$ is an associative H-space, the bar spectral sequence computes the homology of the delooping, $H_{*} (B X)$ . If $X$ is an $n$ -fold loop space for $n \geq 2$ this is a spectral…

L-quadri-algebras

Ligong Liu, Xiang Ni, Chengming Bai

Quadri-algebras introduced by Aguiar and Loday are a class of remarkable Loday algebras. In this paper, we introduce a notion of L-quadri-algebra with 4 operations satisfying certa…

Special symplectic Lie groups and hypersymplectic Lie groups

Xiang Ni, Chengming Bai

A special symplectic Lie group is a triple $(G, ω, \nabla)$ such that $G$ is a finite-dimensional real Lie group and $ω$ is a left invariant symplectic form on $G$ which is parallel…
