Valued Graphs and the Representation Theory of Lie Algebras

open access: yesAxioms, 2012
Quivers (directed graphs), species (a generalization of quivers) and their representations play a key role in many areas of mathematics including combinatorics, geometry, and algebra.

The Stabilized Poincare-Heisenberg algebra: a Clifford algebra viewpoint [PDF]

open access: yes, 2006
The stabilized Poincare-Heisenberg algebra (SPHA) is the Lie algebra of quantum relativistic kinematics generated by fifteen generators. It is obtained from imposing stability conditions after attempting to combine the Lie algebras of quantum mechanics ...

Algebraic bivariant $K$-theory and Leavitt path algebras. [PDF]

open access: yesJournal of Noncommutative Geometry, 2021
We investigate to what extent homotopy invariant, excisive and matrix stable homology theories help one distinguish between the Leavitt path algebras L(E) and L(F ...

Algebraic structure of path-independent quantum control

open access: yesPhysical Review Research, 2022
Path-independent (PI) quantum control has recently been proposed to integrate quantum error correction and quantum control [W.-L. Ma, M. Zhang, Y. Wong, K. Noh, S. Rosenblum, P. Reinhold, R. J. Schoelkopf, and L. Jiang, Phys. Rev. Lett. 125, 110503 (2020)

A Synergy between History of Mathematics and Mathematics Education: A Possible Path from Geometry to Symbolic Algebra

open access: yesEducation Sciences, 2020
This paper proposes an experimental path aimed at guiding upper secondary school students to overcome that discontinuity, often perceived by them, between learning geometry and learning algebra.

Interpolative Boolean algebra based multicriteria routing algorithm [PDF]

open access: yesYugoslav Journal of Operations Research, 2015
In order to improve the quality-of-service of distributed applications, we propose a multi-criteria algorithm based on interpolative Boolean algebra for routing in an overlay network.

基本弱Hopf代数和弱覆盖箭图(Basic weak Hopf algebra and weak covering quiver)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2016
We introduce a finite-dimensional basic and split weak Hopf algebra H over an algebraically closed field k with strongly graded Jacobson radical r. We obtain some structures of a finite-dimensional basic and split semilattice graded weak Hopf algebra,and

The commutative core of a Leavitt path algebra [PDF]

open access: yes, 2018
For any unital commutative ring $R$ and for any graph $E$, we identify the commutative core of the Leavitt path algebra of $E$ with coefficients in $R$, which is a maximal commutative subalgebra of the Leavitt path algebra.
