In this paper we consider a Sturm–Liouville type differential operator with unbounded operator coefficients given on a finite interval, with values in a separable Banach space. In the past, problems of this type have been mainly studied on Hilbert space. Kuelbs (J Funct Anal 5:354–367, 1970) has shown that every separable Banach spacecan be continuously embedded in a separable Hillbert space. Given this result, we first prove that there always exists a separable Banach spaceas a continuous embedding, which is a (conjugate) isometric isomorphic copy of. This space generates a semi-inner product structure forand is the tool we use to develop our theory. We are able to obtain a regularized trace formula for the above differential operator when the problem is posed on. We also provide a few examples illustrating the scope and implications of our approach.
