Skein Algebras and Quantum Groups. The sl_n-skein algebra of a surface provides a quantization of the SL_n(C)-character variety. For surfaces with boundary, this framework extends naturally to the stated skein algebra. We demonstrate how various aspects of quantum groups admit simple and transparent geometric interpretations through the lens of stated skein algebras. In particular, we will present a geometric realization of the dual canonical basis of O_q(sl_3) using skeins."
