Reducibility of linear representations, free ideals, and Kippenhahn's conjecture
Michael Stessin, Rongwei Yang
This paper presents a comprehensive study of the characteristic polynomial of matrix tuples and finite dimensional group representations. Among other things, several key concepts a…
Diophantine analysis and the Braid group
Wei He, Wenhao Lu, Hang Yang +1
Given a finite dimensional representation of a finitely generated group , the associated characteristic polynomial is defined as $Q_π(z):=\de…
The Characteristic Polynomial of Projections
Kate Howell, Rongwei Yang
This paper proves that the characteristic polynomial is a complete unitary invariant for pairs of projection matrices. Some special cases involving three or more projections are al…
Joint spectrum, group representations, and Julia set
Rongwei Yang
The first half of this mostly expository note reviews some notions of joint spectrum of linear operators, and it gives a new characterization of amenable groups in terms of project…
On multi-soliton solutions to the Heisenberg ferromagnetic spin chain equation in (2+1)-dimensions
Zhou-Zheng Kang, Rong-Cao Yang
This paper concentrates on the Heisenberg ferromagnetic spin chain (HFSC) equation in (2+1)-dimensions modelling nonlinear wave propagation in ferromagnetic spin chain. A variable…
2-complex symmetric composition operators on
Lian Hu, Songxiao Li, Rong Yang
In this paper, we study 2-complex symmetric composition operators with the conjugation on the Hardy space . More precisely, we obtain the necessary and sufficient conditio…
