On Commuting Differential Operators of Rank 2 Corresponding to Trigonal Spectral Curves of Genus 3
The construction of ordinary commuting differential operators is a classical problem of differential equations and integrable systems, which has applications in soliton theory. Commuting operators of rank 1 were found by Krichever. The problem of constructing operators of rank \(l>1\) has not been solved in the general case. In all known examples of operators of rank \(l>1\), the spectral curves are hyperelliptic curves. In this paper, the first examples of operators of rank 2, corresponding to trigonal spectral curves of genus 3, are constructed.
