Perturbation-Tolerant Structural Controllability for Linear Systems
Yuan Zhang, Yuanqing Xia, Gang Wang +1
This paper proposes a notion termed perturbation-tolerant structural controllability (PTSC) to study the generic property of controllability preservation/resilience of structured l…
Rank Resilience of Pattern Matrices against Structured Perturbations with Applications
Yuan Zhang, Yuanqing Xia, Gang Wang
In structured system theory, a pattern matrix is a matrix with entries either fixed to zero or free to take arbitrary numbers. The (generic) rank of a pattern matrix is the rank of…
Projective loops generate rational loop groups
Gang Wang, Oliver Goertsches, Erxiao Wang
Rational loops played a central role in Uhlenbeck's construction of harmonic maps into U(n) (chiral model in physics), and they are generated by simple elements with one pole and o…
Dressing Actions on Proper Definite Affine Spheres
Zhicheng Lin, Gang Wang, Erxiao Wang
We will first clarify the loop group formulations for both hyperbolic and elliptic definite affine spheres in R^3. Then we classify the rational elements with 3 poles or 6 poles in…
Some spherical uniqueness theorems for multiple trigonometric series
J. Marshall Ash, Gang Wang
We prove that if a multiple trigonometric series is spherically Abel summable everywhere to an everywhere finite function which is bounded below by an integrable function, t…
