This enables us to recover the operator L from the operator R by solving a system of nonlinear ordinary differential equations.


Domains of fractional powers of ordinary differential operators in spaces Lp


An exact description (in terms of smoothness and specified boundary conditions) is obtained for the domains of fractional powers of an ordinary differential operator of arbitrary order with general boundary conditions, acting in spaces Lp.


It is shown that selfadjoint boundary conditions for ordinary differential operators of odd order are regular in Birkhoff's sense.
