Numerical Range of Two Operators in Semi-Inner Product Spaces [PDF]
Abstract and Applied Analysis, 2012 In this paper, the numerical range for two operators (both linear and nonlinear) have been studied in semi-inner product spaces. The inclusion relations between numerical range, approximate point spectrum, compression spectrum, eigenspectrum, and ...

Numerical Range on Weighted Hardy Spaces as Semi Inner Product Spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 The semi-inner product, in the sense of Lumer, on weighted Hardy space which generate the norm is unique. Also we will discuss some properties of the numerical range of bounded linear operators on weighted Hardy spaces.

Complimentarity problems in semi-inner product spaces
Applied Mathematics Letters, 1990 AbstractIn this paper, we consider and study the complementary problems in the setting of semi-inner product spaces. It has been shown that these problems can be formulated as fixed point problems using the concept of change of variables. This formulation enables us to suggest iterative algorithms for complementarity problems.

Some Gr¨uss Type Inequalities for n-Tuples of Vectors in Semi-Inner Modules
Journal of Mathematical Extension, 2014 . Some Gr¨uss type inequalities in semi-inner product modules over C∗-algebras and H∗-algebras for n-tuples of vectors are established. Also we give their natural applications for the approximation of the discrete Fourier and the Melin transforms in ...

On Relative Reproducing Kernel Banach Spaces: Definitions, Semi-Inner Product and Feature Maps [PDF]
Sahand Communications in Mathematical Analysis, 2023 In this paper, a special class of relative reproducing kernel Banach spaces a semi-inner product is studied. We extend the concept of relative reproducing kernel Hilbert spaces to Banach spaces. We present these relative reproducing kernel Banach spaces

Involve, a Journal of Mathematics, 2022 We formalize the notion of vector semi-inner products and introduce a class of vector seminorms which are built from these maps. The classical Pythagorean theorem and parallelogram law are then generalized to vector seminorms that have a geometric mean closed vector lattice for codomain.

On $(n,m)$-$A$-normal and $(n,m)$-$A$-quasinormal semi-Hilbertian space operators [PDF]
Mathematica Bohemica, 2022 The purpose of the paper is to introduce and study a new class of operators on semi-Hilbertian spaces, i.e. spaces generated by positive semi-definite sesquilinear forms. Let ${\mathcal H}$ be a Hilbert space and let $A$ be a positive bounded operator on
