Quaternionic Quantum q-Oscillator And Unbounded Subnormal Operators In Quantum Economics
T. Prasad, K Krishnan, E. Shine Lal
In this note, we observe that the class of unbounded subnormal operators on quaternionic Hilbert spaces is a solution of quaternionic quantum harmonic q-oscillator whose complex ca…
Some Classes of Absolutely Norm Attaining Weighted Shift operators on Directed Graphs
K Krishnan, T. Prasad, E. Shine Lal
In this paper we study absolutely norm attaining quasi--paranormal weighted shifts on directed graphs and give some examples. Moreover we give some examples which show that t…
Cauchy dual Subnormality of extensions of -isometric composition operators on directed graphs
V. Devadas, T. Prasad, E. Shine Lal
In this paper, we discuss the analyticity, - regularity, kernel condition and subnormality of Cauchy dual of -quasi--isometric composition operators on directed gr…
Extension of m-isometric weighted composition operators on directed graphs
V. Devadas, E. Shine Lal, T. Prasad
In this paper, we discuss k-quasi-m-isometric composition operators and weighted composition operators on directed graphs with one circuit and more than one branching vertex.
