On Compact Operators whose Norms are Eigenvalues
(JOOUST, 2019)The class of compact operators is fundamental in operato_Lllle~+Y.• Char-acterization of compact operators acting on different sp~ces has been fas-cinating to many Mathernaticians., Many properties such as bounded¬ness, ... -
Characterization of Similarity Orbits of Invariant Subspaces of Norm-Attainable Operators.
(Jooust, 2019)Abstract The notion of similarity orbits(S(T)) of Hilbert space operators have been extensively investigated by many researchers such as Herrero, Fialkow and Had• win among others. Various ... -
Orthogonality of Finite Rank Generalized Derivations
(JOOUST, 2020)Properties of derivations have been studied by various mathematicians for instance, norm, numerical range, spectrum, positivity among others. Range-kernel orthogonality is also a property for derivations implemented by ... -
Preparation, Characterization, Optimization and Pre-Clinical Evaluation of Selected Anti-Malarial Drugs Encapsulated into Different Nanocarriers
(JOOUST, 2015)Artemisinin and its derivatives have proved to be very effective against malaria parasites although it has the short falls of low solubility, poor bioavailability and short half-lives. Instead of discarding these drugs it ... -
Rotundity of Norms in Frechet Spaces
(JOOUST, 2019)The notion of rotundity of norms is a very interesting area of research in analysis. The question whether if a norm is Highly Rotund implies it is Midpoint Locally Uniformly Rotund or whether a Uniformly Ro¬tund norm in ... -
