Abstract In this paper, we first consider classes of nonlinear mappings containing the class of firmly nonexpansive mappings which can be deduced from an equilibrium problem in a Hilbert space.
Let $B$ be a real separable Banach space. A suitable linear imbedding of a real separable Hilbert space into $B$ with dense range determines a probability measure on ...
Quantum mechanics remains a cornerstone of modern physics, providing a framework for understanding phenomena at the microscopic scale. At the heart of its formulation lies the concept of Hilbert ...
