A new method for comparing two norm hilbert spaces and their operators
(ELSEVIER SCIENCE BV, 2011)
Compact perturbations of fredholm operators on norm hilbert spaces over krull valued fields
(AMER MATHEMATICAL SOC, 2010)
Weak Convergence Theorems for Maximal Monotone Operators with Nonspreading mappings in a Hilbert space
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2011)
Nonpositive Curvature: A Geometric Approach to Hilbert-Schmidt Operators
(Elsevier Science, 2007-12)
We give a Riemannian structure to the set Σ of positive invertible unitized Hilbert–Schmidt operators, by means of the trace inner product. This metric makes of Σ a nonpositively curved, simply connected and metrically ...
Higher order relative spectrum of linear operators in hilbert spaces
(Universidad de los AndesMaestría en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2019)
Se sabe de la teoría espectral que dado un operador lineal, acotado y autoadjunto en un espacio de Hilbert es difícil detectar los autovalores en brechas de su espectro esencial. En algunos casos para localizar tales ...
Linear homeomorphisms of non-classical Hilbert spaces
(ELSEVIER SCIENCE BV, 1999)
Let K be a complete infinite rank valued field, In [4] we studied Norm Hilbert Spaces (NHS) over K i.e, K-Banach spaces for which closed subspaces admit projections of norm less than or equal to 1. In this paper we prove ...
