Abstract

The Burchnall-Chaundy theory concerns the classification of all pairs of commuting ordinary differential operators. We phrase this theory in the language of spectral data for integrable systems. In particular, we define spectral data for rank 1 commutative algebras AA of ordinary differential operators. We solve the inverse problem for such data, i.e. we prove that the algebra AA is (essentially) uniquely determined by its spectral data. The isomorphy type of AA is uniquely determined by the underlying spectral curve.
