Abstract
The basics of self-adjoint extensions via sesquilinear forms are discussed. The main points are form representations, Friedrichs extensions and examples. Additional information appears in Sections 6.1, 9.3 and 10.4. Some sesquilinear forms can be sources of self-adjoint operators related to “singular interactions” and/or ill-posed operator sums.
