Trace formulas for Schrödinger operators from the view point of complex analysis

Hiroshi Isozaki, Evgeny L. Korotyaev

We consider the Schr{ö}dinger operator $-\Delta +V(x)$ in $L^2({\mathbf{R}}^3)$ with a real short-range (integrable) potential $V$. Using the associated Fredholm determinant, we present new t…
