题目:A new method to prove the nonuniform dichotomy spectrum theorem
报告人:夏永辉 教授(浙江师范大学)
摘要:This paper presents a new method to prove the nonuniform dichotomy spectrum theorem. The authors in [7](Chu, Xia-BSM2015), [17] (Siegmund-JDDE2002), [20](Zhang-JFA2014) employed linear integral manifolds (stable and unstable) to establish the spectral theorem. They then used the spectrum theorem to study reducibility. On the contrary, we employ reducibility to establish the nonuniform dichotomy spectrum based on the technique of mathematical analysis, which is a completely different method to prove the spectrum theorem. This work is joint with Yuzhen Bai and Donel O’Regan.
