On the Generalized Cluster Algebras of Geometric Type
Liqian Bai, Xueqing Chen, Ming Ding +1
We develop and prove the analogs of some results shown in [Berenstein A., Fomin S., Zelevinsky A., Duke Math. J. 126 (2005), 1-52] concerning lower and upper bounds of cluster alge…

On positivity for generalized cluster variables of affine quivers
Xueqing Chen, Ming Ding, Fan Xu
It has been proved in \cite{LS} that cluster variables in cluster algebras of every skew-symmetric cluster algebra are positive. We prove that any regular generalized cluster varia…

Fermionic Novikov algebras admitting invariant non-degenerate symmetric bilinear forms are Novikov algebras
Zhiqi Chen, Ming Ding
This paper is to prove that a fermionic Novikov algebra equipped with an invariant non-degenerate symmetric bilinear form is a Novikov algebra.
