Cluster algebra structure on the finite dimensional representations of for =2

Yan-Min Yang, Zhu-Jun Zheng

In this paper, we prove one case of the conjecture given by Hernandez and Leclerc\cite{HL0}. Specifically, we give a cluster algebra structure on the Grothendieck ring of a full su…

Non-abelian Extensions of Lie 2-algebras

Shaohan Chen, Yunhe Sheng, Zhujun Zheng

In this paper, we introduce the notion of derivations of Lie 2-algebras and construct the associated derivation Lie 3-algebra. We prove that isomorphism classes of non-abelian exte…

Higher Dimensional Homology Algebra V:Injective Resolutions and Derived 2-Functors in ($\cR$-2-Mod)

Fang Huang, Shao-Han Chen, Wei Chen +1

In this paper, we will construct the injective resolution of any $\cR$-2-module, define the right derived 2-functor, and give some related properties of the derived 2-functor in ($…

Higher Dimensional Homology Algebra III:Projective Resolutions and Derived 2-Functors in (2-SGp)

Fang Huang, Shao-Han Chen, Wei Chen +1

In this paper, we will define the derived 2-functor by projective resolution of any symmetric 2-group, and give some related properties of the derived 2-functor.

Higher Dimensional Homology Algebra II:Projectivity

Fang Huang, Shao-Han Chen, Wei Chen +1

In this paper, we will prove that the 2-category (2-SGp) of symmetric 2-groups and 2-category ($\cR$-2-Mod) of $\cR$-2-modules(\cite{5}) have enough projective objects, respectivel…

2-Modules and the Representation of 2-Rings

Fang Huang, Shao-Han Chen, Wei Chen +1

In this paper, we develop 2-dimensional algebraic theory which closely follows the classical theory of modules. The main results are giving definitions of 2-module and the represen…

A Vertex Algebra Commutant for the -System and Howe pairs

Yan-Jun Chu, Fang Huang, Zhu-Jun Zheng

Analogue to commutants in the theory of associative algebras, one can construct a new subalgebra of vertex algebra known as a vertex algebra commutant. In this paper, for the adjoi…

Topological quantum field theory and crossing number

Zhujun Zheng, Ke Wu, Shikun Wang +1

In this paper, we construct a new topological quantum field theory of cohomological type and show that its partition function is a crossing number.
