    "abstract": "Multiparameter quantum gl(N) is not a rigid structure. This paper defines an\nessential deformation as one that cannot be interpreted in terms of a\nsimilarity transformation, nor as a perturbation of the parameters. All the\nequivalence classes of first order essential deformations are found, as well as\na class of exact deformations. This work provides quantization of all the\nclassical Lie bialgebra structures (constant r-matrices) found by Belavin and\nDrinfeld for sl(n). A special case, that requires the Hecke parameter to be a\ncubic root of unity, stands out.",
