On almost similarity results on partial isometrics, 𝛉- operators and posinormal operators
(International Journal of Statistics and Applied Mathematics, 2021-06)It is pre-eminent that equality of spectra is realized when the two given operators are unitarily equivalent or similar but not when they are almost similar. Also, projections which are 𝛼-almost similar, demonstrate ... -
ON CLASSIFICATION OF PERMUTATIONS
(Asia Pac Journal, 2020-03)Some researchers in combinatorics have developed permutation algorithms using different approaches. We contribute to this area by developing a formula for generating permutations whereby, starting with an identity ... -
On the Numerical Ranges
(International Journal of Scientific and Innovative Mathematical Research (IJSIMR), 2015-08)Properties of operators in a C*-algebra B(H) have been studied by many researchers in operator theory. This paper is an investigation of the numerical ranges of operators in B(H) . We show that zero is in the algebraic ... -
On the Norm of Elementary Operator
(Advances in Pure Mathematics, 2014-07)The norm of an elementary operator has been studied by many mathematicians. Varied results have been established especially on the lower bound of this norm. Here, we attempt the same problem for finite dimensional operators. -
On Norm of Elementary Operator of Length Two
(International Journal of Scientific and Innovative Mathematical Research (IJSIMR), 2017-06)Norms of elementary operators have been studied by many mathematicians.
