. We discuss the qq -systems, the functional form of the Bethe ansatz equations for the twisted Gaudin model from a new geometric point of view. We use a concept of G -Wronskians, which are certain meromorphic sections of principal G -bundles on the projective line. In this context, the qq -system, similar to its difference analog, is realized as the relation between generalized minors of the G -Wronskian. We explain the link between G -Wronskians and twisted G -oper connections, which are the traditional source for the qq -systems.
