Nonselfadjoint Schrödinger operators with singular first-order coefficients. (English) Zbl 0555.35025
The operator of the form \(T=(i\nabla +b)^ 2+a\nabla +q\) in \(L^ 2(R^ m)\) with domain \(C_ 0^{\infty}(R^ m)\) is considered. If a, b are real valued vector functions such that \(b\in L^ 4_{loc}\), \(div b\in L^ 2_{loc},\) \((1+| x|)^{-1}a\in L^ 4+L^{\infty},\) \(div a\in L^{\infty}\) and \(q\in L^ 2_{loc}\), Re \(q\geq 0\), then the essential-m-accretivity of the operator T is proved.
