Dual canonical basis
I will talk about the dual canonical basis of type A. Mainly,
I will focus on the following topics:
- The construction of the dual canonical basis of type A.
- The bar action and the exponential nature.
- The positivity of the multiplication.
- The relationship between dual canonical basis and the subalgebra of
