    • On generalised triplets of Hilbert spaces 

      Cojuhari, P.; Gheondea, Aurelian (Editura Academiei Romane, 2020)
      We compare the concept of triplet of closely embedded Hilbert spaces with that of generalised triplet of Hilbert spaces in the sense of Berezanskii by showing when they coincide, when they are different, and when starting ...

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

      Cojuhari, P.; Gheondea, A. (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 

      Cojuhari, P.; Gheondea, A. (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 ...
