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 ...

Hilbert spaces provide a fundamental mathematical framework for analysing infinite-dimensional vector spaces endowed with an inner product. In the context of stochastic processes, these spaces serve ...

This paper compares the method of Tikhonov regularization as advanced in 1963 with the more recent approach utilizing the theory of reproducing kernel Hilbert spaces (RKHS). The methods are shown to ...
