Talk Titles: (1) Positive linear maps on matrix algebras

Abstract:  The notion of sums of squares is very much related to the structure theory of linear maps on matrix algebras. Here, we look into the down-to-earth construction of completely positive linear maps in connection with quantum information.

(2) Non-commutative magic  everywhere.

Abstract:  Suddenly, there arrives the era of quantum computers, where matrix analysis plays an important role in all sorts of applications. Here, I will show off some magic of non-commutative computations.
