Research in Hilbert space operators and Berezin numbers constitutes a fertile arena in modern mathematical analysis, bridging abstract operator theory with practical applications in spectral theory ...

In search of a united scientific theory, a new quantum gravity paper might have proposed an interesting aspect that made the ...

In this paper we determine the relationship between the spectra of a continuous contraction semigroup on Hilbert space and properties of the resolvent of its infinitesimal generator. The methods rely ...

This paper extends two recent improvements in the Hilbert space setting of the well-known Katznelson-Tzafriri theorem by establishing both a version of the result valid for bounded representations of ...

Stochastic analysis in Hilbert and Banach spaces represents a dynamic and rapidly evolving field at the intersection of probability theory and functional analysis. In these infinite-dimensional ...
