Properties of Spectrally Bounded Compact Elementary Operators
(DOI: 10.47443/cm.2021.0012, 2021-03-31)
Spectrally bounded compact elementary operators on dense irreducible subalgebras of C ∗ -algebras are characterized. Also, it is shown that left multiplications, right multiplications, generalized derivations and basic ...
Assets Valuation Using a Contingent Claim
(International Journal of Science and Research (IJSR), 2017-02)
In this paper we consider the price dynamics of a portfolio consisting of risk-free and risky assets. The paper discusses the pricing process of a contingent claim, the pricing equation and the risk-neutral valuation under ...
On denseness of similarity orbits of norm-attainable operators
(International Journal of Advances in Applied Mathematics and Mechanics, 4/16/2019)
The notion of dense sets has been extensively discussed on both metric and topological spaces. Various properties of the sets have been proved under the underlying spaces. However, if we consider these sets to be from ...
On Compact Operators Whose Norms Are Eigenvalues and Completeness
(International Journal of Contemporary Mathematical Sciences, 2/21/2018)
Let X be a Banach space and T: X→Y be a linear operator, then Tis compact if it maps bounded sequences in X to sequences in Y with convergent subsequences, that is, if xn ∈ X is a bounded sequence, then T xn ∈ Y has a ...
On Compactness of Similarity Orbits of Norm-Attainable Operators
(International Journal of Mathematics And its Applications, 2019)
The notion of compactness plays an important role in analysis. It has been extensively discussed on both metric and topological spaces. Various properties of compactness have been proved under the underlying spaces. However, ...
Characterization of Norm-Attainable Operators
(International Journal of Mathematical Archive, 7/13/2018)
In this paper we characterize norm-attainable elementary operators, we show that 𝛿 𝑃,𝑄 is norm-attainable if both P and Q are norm-attainable and𝛿𝑃,𝑄 is norm-attainable 𝛿𝑃,𝑄if is normally represented.
On Tensor Products and Elementary Operators
(Core, 2018)
In this paper we describe operator systems and elementary operators via tensor products. We also discuss norms of elementary operators.
Conditions for Positivity of Operators in Non-unital C*-algebras
(International Journal of Mathematical Analysis, 1/9/2015)
In this paper, we present results on the necessary and sufficient condi-tions for positivity of operators in non-unital C*- algebras
International Journal of Statistics and Applied Mathematics 2018; 3(4): 74-84 Reconstructing earth observation vegetation index records with a Bayesian spatiotemporal dynamic model
(International Journal of Statistics and Applied Mathematics, 2018-01)
Long-term vegetation index records derived from Earth observation facilitate the characterization of ecosystem response to climate variability and change. The presence of atmospheric components and radiometric inconsistencies ...
Mathematical modelling of HIV infection
(IJMA, 2013)
We formulate a deterministic mathematical model for the HIV/AIDS.
