Regular Ordinary Differential Operators with Involution

Mathematical Notes, 2019
The paper under review deals with the operators defined on a finite closed interval by differential expressions of the form \[L(y)=JP(y)+Q(y), \quad y=y(x), \quad x\in[-1,1],\] where \[P(y)=y^{(n)}(x)+\sum_{k=1}^{n} p_k (x)y^{(n-k)},\;\; Q(y)=y^{(m)}(x)+\sum_{k=1}^{m} q_k (x)y^{(m-k)};\] \(J\) is the involution operator \(Jy(x)=y(-x)\) and the ...
