Geometry of the projective unitary group of a C*-algebra
(Unión Matemática Argentina, 2017-06)
Let A be a C∗-algebra with a faithful state ϕ. It is proved thatthe projective unitary group P UA of A,P UA = UA/T.1,(UA denotes the unitary group of A) is a C∞-submanifold of the Banach spaceBs(A) of bounded operators ...

The objective of this research is to understand the role of digital technologies (DT) in educational processes associated with Linear Algebra in four distance teacher education in mathematics courses linked to the Open ...
Método dos mínimos quadrados aplicado a um problema de geoposicionamento
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Matemática em Rede NacionalUTFPR, 2018-02-08)
The main goal of this work is to present the least squares method to solve overdetermined linear systems, that is, systems of the form Ax = b , where A m×n , with m > n . In this sense, we showed that the resolution of ...
Geodesics of projections in von neumann algebras
(American Mathematical Society, 2021-07)
Let A be a von Neumann algebra and PA the manifold of projections in A. There is a natural linear connection in PA, which in the finite dimensional case coincides with the the Levi-Civita connection of the Grassmann manifold ...
