Title:On a relative version of the Krichever correspondence
View PDFAbstract: For a given base scheme, a correspondence is established between a class of sheaves on curves over this base scheme and certain points of infinite Grassmannians. This equivalence extends to a characterization of commutative algebras of ordinary differential operators with coefficients in the ring of formal power series over a given $k$-algebra. Our construction generalizes the approach of this http URL, which gives the above connection in the case that the base scheme is one closed point.
