comment Do we have $\mathbb{C}[SL_n] = \oplus_{\lambda, \text{ht}(\lambda)\leq n} V_{\lambda} $?

comment A question about the dual map of $A \otimes B \to B$.
\begin{align} & \phi(E,a)=0, \ \phi(E,b)=1, \ \phi(E,c)=0, \ \phi(E,d)=0, \\ & \phi(F,a)=0, \ \phi(F,b)=0, \ \phi(F,c)=1, \ \phi(F,d)=0, \\ & \phi(K,a)=q, \ \phi(K,b)=0, \ \phi(K,c)=0, \ \phi(K,d)=q^{-1}. \end{align} Therefore we can obtain $\delta$ by using this pairing. Is this correct?
