Speaker: Tran Nhat Tan, Hokkaido University
Time: 9h00, Thursday, February 25, 2016 Location: Room 6, Building A14, Institute of Mathematics, 18 Hoang Quoc Viet, Cau Giay, Hanoi Abstract: We study combinatorial and geometric properties of root systems concerning exponents of Weyl group and coefficients of the highest root. The study allows us to provide an elementary proof of an observation that the second exponent is one plus the largest coefficient |
