Abstract

To every solution of the unparametrized Yang–Baxter equation there is associated a bialgebra, which is generated by an analog of the Chevalley generators of semisimple Lie algebras. The q‐deformed algebras Uq(g) are recovered as special cases, the algebra of Faddeev–Reshetikhin–Takhtadzhyan is contained as a subalgebra. A geometrical interpretation of the algebra is given, which hints at some connection to Dotsenko–Fateev models of two‐dimensional conformal quantum fields and perturbations thereof.
