AMSS scientist Prof. Duan Haibao was awarded with the 2nd prize of the National Natural Science Prize for his outstanding research achievements in his work “Multiplicative rule of Schubert classes”.

Prof. Duan Haibao obtained a unified formula for multiplying Schubert classes in a flag manifold. It reduces the structure constants directly to the Cartan numbers of the Lie group involved, and is effective. The method and tools developed in establishing the formula has also been extended and applied to other classical topics concerning the geometry of flag manifolds and homogeneous spaces.  Besides, he has received Chern rize in Mathematics in 2005.

The National Natural Science Prize is China's most prestigious award in natural science. The award is to recognize achievements in various fields of natural science that bring significant advancement in scientific knowledge.
