Query: On the classical R-matrix of the degenerate Calogero-Moser models   The most general momentum independent dynamical r-matrices are described for
the standard Lax representation of the degenerate Calogero-Moser models based
on $gl_n$ and those r-matrices whose dynamical dependence can be gauged away
are selected. In the rational case, a non-dynamical r-matrix resulting from
gauge transformation is given explicitly as an antisymmetric solution of the
classical Yang-Baxter equation that belongs to the Frobenius subalgebra of
$gl_n$ consisting of the matrices with vanishing last row.
