A Quaternionic Hansen--Pedersen Inequality and its Application to -Transforms
M. Fashandi
We establish a quaternionic Hansen--Pedersen inequality for real operator-convex functions on right quaternionic Hilbert spaces. The proof is based on the continuous real functiona…

Some inequalities for log-convex functions of selfadjoint operators on quaternionic Hilbert spaces
Massoumeh Fashandi
In this paper, some Jensen's type inequalities between quaternionic bounded selfadjoint operators on quaternionic Hilbert spaces are proved, using a log-convex function. Also, by a…

On p-hyponormal operators on quaternionic Hilbert spaces
Massoumeh Fashandi
This paper extends the notion of a p-hyponormal operator for a bounded right linear quaternionic operator defined on a right quaternionic Hilbert space. Several fundamental propert…
