Abstract
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=−Δ+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.
