A triangular decomposition for the crystal lattice of quantized function algebras

Saikat Das, Ayan Dey, Arup Kumar Pal

We prove a triangular decomposition theorem for the lower crystal lattice ${\mathcal{O}}_t^{A_0}(G)$ of the quantized function algebra ${\mathcal{O}}_t^{}(G)$, where $G$ is a con…
