Abstract:
We refine the notion of a Darboux transformation for differential operators of an order higher than two and consider commutative rings of differential operators that are invariant under the group of dilations of the independent variable.
Keywords:
Darboux transformation, commutative ring of differential operators, third-order Bessel equation.
