Difference Cochains and Reidemeister Traces
《Chinese Annals of Mathematics,Series B》2017年第6期1365-1372,共8页Baoqun ZHANG Xuezhi ZHAO 
supported by the National Natural Science Foundation of China(Nos.11431009,11661131004)
The authors consider the difference of Reidemeister traces and difference cochain of given two self-maps, and find out a relation involving these two invariants.As an application, an inductive formula of the Reidemeis...

On 2 - 3 Matrix Chevalley Eilenberg Cohomology
《Advances in Pure Mathematics》2015年第14期835-849,共15页Joseph Dongho Epizitone Duebe-Abi Shuntah Roland Yotcha 
The main objective of this paper is to provide the tool rather than the classical adjoint representation of Lie algebra;which is essential in the conception of the Chevalley Eilenberg Cohomology. We introduce the noti...

Duality for cochain DG algebras被引量：3
《Science China Mathematics》2013年第1期79-89,共11页JφRGENSEN Peter 
This paper develops a duality theory for connected cochain DG algebras,with particular emphasis on the non-commutative aspects.One of the main items is a dualizing DG module which induces a duality between the derived...

Partial expansion of a Lipschitz domain and some applications
《Frontiers of Mathematics in China》2012年第2期249-272,共24页Jay Gopalakrishnan Weifeng Qiu 
We show that a Lipschitz domain can be expanded solely near a part of its boundary, assuming that the part is enclosed by a piecewise C1 curve. The expanded domain as well as the extended part are both Lipschitz. We a...
