We investigate the spectrum of a differential operator of fourth order with bounded operator coefficients and find a formula for the trace of this operator.

We will obtain a formula for the trace of the Sturm–Liouville operator with operator coefficient.

In this work, a formula for the regularized trace of second order differential operator given in a finite interval which has unbounded operator coefficients is found.

Malignant peripheral nerve sheath tumors are rare in the head and neck region. A tumor arising in the intraparotid region of the facial nerve, suggestive of pleomorphic adenoma preoperatively is… (More)
