    • ON THE NORM OF AN ELEMENTARY OPERATOR OF FINITE LENGTH IN A 𝑪∗ALGEBRA 

      Kawira, Esther; King'ang'i, Dennis, N.; Musundi, Sammy, W. (Journal of Progressive Research in Mathematics(JPRM), 2018)
      Properties of elementary operators have been studied over the past years especially the norm aspect. Various results have been obtained on elementary operatorsof different lengths using different approaches. ...

    • On the Norm of Basic Elementary Operator in a Tensor Product 

      Muiruri, Peter; King'ang'i, Denis; Musundi, Sammy (International Journal of Scientific and Innovative Mathematical Research., 2019)
      In this paper, we determine the norm of an elementary operator in a tensor product. More precisely, we investigate the bounds of the norm of a basic elementary operator in a tensor product. We employ the techniques of ...

    • On Unitary Invariance of Some Classes of Operators in Hilbert Spaces 

      Muhati, Linety N.; Khalagai, J. M. (Pure Mathematical Sciences, 2020)
      It is a known fact in operator theory that two similar operators have equal spectra but they do not necessarily have to belong to the same class of operators. However, under the stronger relation of unitary equivalence ...

    • Optimal Kiefer Ordering of Simplex Designs for Third-Degree Mixture Kronecker-Models with three ingredients. 

      Korir, Betty (Mathematical Theory and Modeling, 2019)
      This paper investigates the Kiefer optimality in the third-degree Kronecker model for mixture experiments. For mixture models on the simplex, a better design is obtained, by matrix majorization that yields a larger ...

    • Optimization of Split-Plot Design in the Context of Mixture Process Variable Settings 

      Wanyonyi, Samson W.; et al. (Asian Journal of Probability and Statistics, 2021-04)
      In the presence of process variables, a mixture design has become well-known in statistical modeling due to its utility in modeling the blending surface, which empirically predicts any mixture's response and serves as the ...

    • Parametric Interval Estimation of the Geeta Distribution 

      Kinyanjui, Josphat; Korir, Betty (International Journal of Statistics and Probability, 2018)
      t is well known that the sample mean is the estimator of a population mean in mathematical statistics from a given population of interest as a point estimator which assume a single number that is obtained ...

    • Parametric Point Estimation of the Geeta Distribution 

      Korir, Betty (International Journal of Statistical Distributions and Applications, 2018)
      Geeta distribution is a new discrete random variable distribution defined over all the positive integers with two parameters. This distribution belongs to the family of Location-parameter (LDPD) system and is of the form ...
