Trace formulas applied to the Riemann $ζ$ -function

Mark S. Ashbaugh, Fritz Gesztesy, Lotfi Hermi +3

We use a spectral theory perspective to reconsider properties of the Riemann zeta function. In particular, new integral representations are derived and used to present its value at…

On traces and modified Fredholm determinants for half-line Schrödinger operators with purely discrete spectra

Fritz Gesztesy, Klaus Kirsten

After recalling a fundamental identity relating traces and modified Fredholm determinants, we apply it to a class of half-line Schrödinger operators $(- d^{2} / d x^{2}) + q$ on $(0,\inft…

Some Remarks on the Operator T^*T

Fritz Gesztesy, Konrad Schmüdgen

This note deals with the operator $T^{*} T$ , where $T$ is a densely defined operator on a complex Hilbert space. We reprove a recent result of Z. Sebestyén and Zs. Tarcsay [13]: If $T…
