Shuoyang Xu (Shanghai/Uppsala) holds a seminar with the title "Lie bialgebra structure of derivation Lie algebra over quantum torus". Welcome to join!

**Abstract: **A Lie bialgebra is a vector space endowed simultaneously with a structure of a Lie algebra and a structure of a Lie coalgebra satisfying some compatibility conditions.

In this talk, we discuss the Lie bialgebra structure of derivation Lie algebra over rank d ≥ 3 quantum torus. In the first part of the talk, I will introduce some concepts of Lie bialgebras and derivation Lie algebra over quantum torus. In the second part of the talk, I will show all bialgebra structures on the Lie algebra which we studied are triangular coboundary.

This is a seminar in our algebra seminar series.
