Generalized Krein – von Neumann extension
Our long term plan is to develop a unified approach to prove decomposition theorems in different structures. In our anti-dual pair setting, it would be useful to have a tool which is analogous to the so-called Schur complementation. To this aim, I will present a suitable generalization of the classical Krein – von Neumann extension.
The talk is based on joint work with Zs. Tarcsay (Eötvös Loránd University).
