D. Gurevich et V. Rubtsov, QUANTIZATION OF POISSON PENCILS AND GENERALIZED LIE-ALGEBRAS, Theoretical and mathematical physics, 103(3), 1995, pp. 713-722
We describe two types of Poisson pencils generated by a linear bracket
and a quadratic one arising from a classical R-matrix. A quantization
scheme is discussed for each. The quantum algebras are represented as
the enveloping algebras of ''generalized Lie algebras.''
