    "abstract": "Four results are given that address the existence, ambiguities and\nconstruction of a classical R-matrix given a Lax pair. They enable the uniform\nconstruction of R-matrices in terms of any generalized inverse of $ad L$. For\ngeneric $L$ a generalized inverse (and indeed the Moore-Penrose inverse) is\nexplicitly constructed. The R-matrices are in general momentum dependent and\ndynamical. The construction applies equally to Lax matrices with spectral\nparameter.",
