The nonlocal problem for the $2n$ differential equations with unbounded operator coefficients and the involution
We study a problem with periodic boundary conditions for a $2n$-order differential equation whose coefficients are non-self-adjoint operators. It is established that the operator of the problem has two invariant subspaces generated by the involution operator and two subsystems of the system of eigen...
