• #### Triplets of closely embedded Dirichlet type spaces on the unit polydisc ﻿

(Birkhaeuser Science, 2013)
We propose a general concept of triplet of Hilbert spaces with closed embeddings, instead of continuous ones, and we show how rather general weighted L2 spaces yield this kind of generalized triplets of Hilbert spaces for ...
• #### Triplets of closely embedded Hilbert spaces ﻿

(Springer, 2014)
We obtain a general concept of triplet of Hilbert spaces with closed (unbounded) embeddings instead of continuous (bounded) ones. We provide a model and an abstract theorem as well for a triplet of closely embedded Hilbert ...
