Schrödinger operators with a singular potential
Summary: This note is devoted to the study of some Schrödinger operators with a singular real potential \(Q\). The potential \(Q\) is chosen so that the algebraic sum \(L = - \Delta + Q\) is not defined. Next, we define the sum form operator which will be well defined and we show that this operator verifies the well-known Kato's square root problem.
