弱entwining結構的cup積
發(fā)布時間:2018-12-26 14:53
【摘要】:給出了弱entwining結構上同調(diào)的2種cup積,并證明了它們都是求導度為1的分次結合代數(shù),同時證明了弱entwining結構的復形是弱comp代數(shù),利用其結論得到了2種cup積結構的關系,推廣了雙代數(shù)的Gerstenhaber-Schack理論.
[Abstract]:In this paper, we give two kinds of cup products of cohomology of weak entwining structures, and prove that they are graded associative algebras with derivative degree 1. At the same time, we prove that the complex of weak entwining structures is weak comp algebras. The Gerstenhaber-Schack theory of bialgebra is generalized.
