Abstract
We consider the papers related to the spectrum and the trace formula of a differential operator of second order with unbounded operator coefficient. Reviewing them, we examine what the spectrum is and how to find the trace formula of the operator.
Keywords: Hilbert space; self-adjoint operator; kernel operator; spectrum; essential spectrum; resolvent.
