Invariance of deficiency indices of Hermitian subspaces under relatively bounded perturbations
Yan Liu, Yuming Shi
This paper is concerned with the stability of deficiency indices of Hermitian subspaces (i.e., linear relations) under relatively bounded perturbations in Hilbert spaces. Several r…

Some criteria of chaos in non-autonomous discrete systems
Hua Shao, Guanrong Chen, Yuming Shi
This paper establishes some criteria of chaos in non-autonomous discrete systems. Several criteria of strong Li-Yorke chaos are given. Based on these results, some criteria of dist…

Topological conjugacy between induced non-autonomous set-valued systems and subshifts of finite type
Hua Shao, Guanrong Chen, Yuming Shi
This paper establishes topological (equi-)semiconjugacy and (equi-)conjugacy between induced non-autonomous set-valued systems and subshifts of finite type. First, some necessary a…
