Title: Multiplicative spectrum and trace preservers on complex and stochastic matrices

 

 

Abstract: In this talk, we mainly explore multiplicative spectrum and trace preservers on the set of complex and stochastic matrices. We will give concrete description of spectrum and trace preservers on the sets of complex matrices, doubly stochastic, row stochastic, and column stochastic, respectively. Some related examples and results are provided.
