Functional Models of Abelian Locally von Neumann Algebras and Direct Integrals of Locally Hilbert Spaces

Aurelian Gheondea, Chaitanya J. Kulkarni, Santhosh Kumar Pamula

We obtain a functional model for an arbitrary Abelian locally von Neumann algebra acting on a representing locally Hilbert space under the assumption that the index directed set is…

Forcing confidence: a Process Tracing approach with a dynamical systems model

Alexandra Gheondea-Eladi, Aurelian Gheondea

We propose a continuous time dynamical system model for tracing the evolution of confidence in a small decision making group by consensus with the possibility that a forcing factor…

An Operator Theoretical Approach to Mercer's Theorem

Aurelian Gheondea

This is a survey article on Mercer's Theorem in its most general form and its relations with the theory of reproducing kernel Hilbert spaces and the spectral theory of compact oper…

Localised Operator Valued Kernels Invariant under Actions of -Semigroupoids

Aurelian Gheondea

We consider positive semidefinite kernels which have values given by bounded linear operators on certain bundles of Hilbert spaces and which are invariant under actions of -semi…

Representing Locally Hilbert Spaces and Functional Models for Locally Normal Operators

Aurelian Gheondea

The aim of this article is to explore in all remaining aspects the spectral theory of locally normal operators. In a previous article we proved the spectral theorem in terms of loc…

Localisation of Regularised and Multiview Support Vector Machine Learning

Aurelian Gheondea, Cankat Tilki

We prove a few representer theorems for a localised version of the regularised and multiview support vector machine learning problem introduced by H.Q. Minh, L. Bazzani, and V. Mur…
