Linear Dynamical Systems over Finite Rings
Guangwu Xu, Yi Ming Zou
The problem of linking the structure of a finite linear dynamical system with its dynamics is well understood when the phase space is a vector space over a finite field. The cycle…
On stars and Steiner stars. II
Adrian Dumitrescu, Csaba D. Tóth, Guangwu Xu
A {\em Steiner star} for a set of points in $\RR^d$ connects an arbitrary center point to all points of , while a {\em star} connects a point to the remaining $…
Fast Arithmetics Using Chinese Remaindering
George Davida, Bruce Litow, Guangwu Xu
In this paper, some issues concerning the Chinese remaindering representation are discussed. Some new converting methods, including an efficient probabilistic algorithm based on a…
On Recovery of Sparse Signals via Minimization
T. Tony Cai, Guangwu Xu, Jun Zhang
This article considers constrained minimization methods for the recovery of high dimensional sparse signals in three settings: noiseless, bounded error and Gaussian noise.…
