Semigroup properties of Schrödinger operators with complex singular potentials

Vladimir Mikhailets, Volodymyr Molyboga

In the complex Hilbert space $L_2({\mathbb{R}}_{+})$ on the half-line ${\mathbb{R}}_{+}=[0,\infty )$, we investigate non-symmetric Schrödinger operators \[ Su = -u'' + qu, \qquad u(0) =…
