On commuting differential operators
Electronic Journal of Differential Equations, 2000 Let \(F\) be an ordinary differential field of characteristic \(0\), \(D\) be a differentiation of \(F\), \(C\) be its field of constants and \(R=F[D]\) be a ring of linear differential operators over \(F\)(in other terms a skew polynomial ring). The author discusses in the paper operators from \(R\) which have certain symmetry properties (so-called ...
