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 ...

Two data analytic research areas—"penalized splines and reproducing kernel methods"—have become very vibrant since the mid-1990s. This article shows how the former can be embedded in the latter via ...

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 ...
