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…

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.
