Summary: We present a certain construction of a noncommutative join space formed by linear ordinary differential operators of second order. The basic structure constructed is a quasi-ordered group of operators involving transformations of corresponding homogeneous differential equations by translations. Algebraically significant properties of the structures obtained are also treated.For the entire collection see [Zbl 1097.34001].
