Alzheimer's disease is a complex, multi-factorial, and multi-parametric neurodegenerative etiology. Mathematical models can help understand such a complex problem by providing a way to explore and conceptualize principles, merging biological knowledg

The Dirichlet space is one of the three fundamental Hilbert spaces of holomorphic functions on the unit disk. It boasts a rich and beautiful theory, yet at the same time remains a source of challenging open problems and a subject of active mathematic

The Hilbert L-matrix A s = [ a i j ( s ) ] , where a i j ( s ) = 1 / ( max { i , j } + s ) with i , j ≥ 0 , was introduced in [3] . As a surprising property, we showed that its 2-norm is constant for s ≥ s 0 , where the critical point s 0 is

These operators generalize the Hilbert matrix and connect to several problems in function theory such as the Nehari, Carathéodory–Fejér, and Nevanlinna–Pick problems.

This chapter emphasizes the Hilbert-space properties of these operators. In particular, we study the boundedness, norm, adjoint, and spectral properties of Hilbert transforms and how these properties relate to harmonic conjugation and Riemann–Hilbe
