Linear Combinations of Isometries
Rocky Mountain Journal of Mathematics, 2004 Let \(MI\) denote the set of all scalar multiples of all isometries in a Hilbert space \(H\). In this paper, the authors investigate finite-dimensional linear spaces contained in \(MI\) and the commutativity of such spaces. The authors also present an example of two unilateral shifts \(A\), \(B\) of infinite multiplicity such that span\((A,B)\subset MI\

Nonlinear Analysis, 2019 In this paper, we introduce the concept of enhanced probabilistic metric space (briefly EPM-space) as a type of probabilistic metric space. Also, we investigate the existence of fixed points for a (finite or infinite) linear combination of different ...

Linear combination of chi-squares for multinomial process monitoring
Gestão & Produção, 2021 : Marcucci (1985) proposed a chi square goodness of fit statistic based generalized p-chart for multinomial process monitoring. A chi square distribution quantile was considered as a control chart limit.

On Linear Combinations of Harmonic Mappings Convex in the Horizontal Direction
Universal Journal of Mathematics and ApplicationsThe process of creating univalent harmonic mappings which are not analytic is not simple or straightforward. One efficient method for constructing desired univalent harmonic maps is by taking the linear combination of two suitable harmonic maps. In this

Linear combinations of hypernormal operators
Rocky Mountain Journal of Mathematics, 1988 It is well known that if every operator in the linear span of two normal operators \(N_ 1\) and \(N_ 2\) is normal, then \(N_ 1\) and \(N_ 2\) commute. In this paper, the authors consider this question for hyponormal operators. They give an example of two noncommuting hyponormal operators such that their span consists entirely of hyponormal operators ...

Optimization and selection of Galileo triple-frequency carrier linear combination
Measurement + Control, 2021 The triple-frequency linear combination with a low noise, a long wavelength, and a weak ionosphere is beneficial to effectively eliminate or weaken the common errors, advance the reliability of cycle slip detection and repair, and speed up the ...
