Qiaoling Wei, Meirong Zhang
We introduce a new dynamical system model called the shadowing problem, where a shadower chases after an escaper by always staring at and keeping the distance from him. When the es…

Twist automorphisms and Poisson structures
Yoshiyuki Kimura, Fan Qin, Qiaoling Wei
We introduce (quantum) twist automorphisms for upper cluster algebras and cluster Poisson algebras with coefficients. Our constructions generalize the twist automorphisms for quant…
