We construct a two-parameters example of pseudo-bosons, and we show that they are not regular, in the sense previously introduced by the author. In particular, we show that two biorthogonal bases of L2(R) can be constructed, which are not Riesz bases, in general.

Abstract
We construct a two-parameters example of pseudo-bosons, and we show that they are not regular, in the sense previously introduced by the author. In particular, we show that two biorthogonal bases of L2(R) can be constructed, which are not Riesz bases, in general.File in questo prodotto:
