B-spline interpolation problem in Hilbert C*-modules
Rasoul Eskandari, Michael Frank, Vladimir Manuilov +1
We introduce the -spline interpolation problem corresponding to a -valued sesquilinear form on a Hilbert -module and study its basic properties as well as the uniquene…
Extensions of the Lax-Milgram theorem to Hilbert C*-modules
R. Eskandari, M. Frank, V. M. Manuilov +1
We present three versions of the Lax-Milgram theorem in the framework of Hilbert C*-modules, two for those over W*-algebras and one for those over C*-algebras of compact operators.…
Orthogonally -Jensen mappings on -modules
Ali Zamani
We investigate the representation of the so-called orthogonally -Jensen mappings acting on -modules. More precisely, let be a unital -algebra with the u…
Characterization of numerical radius parallelism in -algebras
Ali Zamani
Let be the numerical radius of an element in a -algebra . First, we prove several numerical radius inequalities in . Particularly, we pr…
Orthogonality preserving property for pairs of operators on Hilbert -modules
Michael Frank, M. S. Moslehian, Ali Zamani
We investigate the orthogonality preserving property for pairs of mappings on inner product -modules extending existing results for a single orthogonality-preserving mapping.…
Characterizations of operator Birkhoff-James orthogonality
Mohammad Sal Moslehian, Ali Zamani
In this paper, we obtain some characterizations of the (strong) Birkhoff--James orthogonality for elements of Hilbert -modules and certain elements of $\mathbb{B}(\mathscr{H})…
