Quantum frobenius homomorphism

Definition

The quantum Frobenius homomorphism is a mathematical concept that generalizes the classical Frobenius homomorphism to the realm of quantum groups and noncommutative geometry. It plays a critical role in understanding the structure of quantum groups, particularly in the context of Drinfeld-Jimbo quantum groups, by relating them to their classical counterparts and enabling the study of their representation theory.
