Non-semi-bounded closed symmetric forms associated with a generalized Friedrichs extension
Non-semi-bounded closed symmetric forms associated with a generalized Friedrichs extension
The theory of closed sesquilinear forms in the non-semi-bounded situation exhibits some new features, as opposed to the semi-bounded situation. In particular, there can be more than one closed form associated with the generalized Friedrichs extension S F of a non-semi-bounded symmetric operator S (if S F exists). However, there …
