We show that well known Sobolev spaces can quite naturally be treated as Pontryagin spaces. This point of view gives a possibility to obtain new properties for some traditional objects such as simplest differential operators.
Keywords: Function spaces, Pontryagin spaces, selfadjoint operators, differential operators.
