Title2: Hankel determinants and irrationality exponents

Speaker:  Prof. Zhixiong Wen  ( Huazhong University of Science and Technology )

Inviter: Prof. Ming Wu and Prof. Bing Li 

Abstract2:

      Irrationality exponents describe the approximation speed of irrationals by rational numbers. In this talk, we should explain how to compute the Hankel determinants of some automatic transcendent numbers, and then discuss the relationship between the Hankel determinants and the irrationality exponents of these automatic transcendent numbers.
