Operator convex functions and their applications
V. Kaleibary, M. R. Jabbarzadeh, S. Furuichi
In this paper, we introduce operator geodesically convex and operator convex-log functions and characterize some properties of them. Then apply these classes of functions to presen…
On the operator Aczél inequality and its reverse
Shigeru Furuichi, Mohammad Reza Jabbarzadeh, Venus Kaleibary
In this paper, we present some operator and eigenvalue inequalities involving operator monotone, doubly concave and doubly convex functions. These inequalities provide some variant…
Spectral radius algebras of wce operators
Yousef Estaremi, Mohammad Reza Jabbarzadeh
In this paper, we investigate the spectral radius al- gebras related to the weighted conditional expectation operators on the Hilbert spaces L2(F). We give a large classes of opera…
Substitution operators on the space of formal power series with a weighted cauchy product
Yousef Estaremi, Mohammad Reza Jabbarzadeh
Boundedness of -substitution operator on , with a weighted Cauchy product , is investigated by an inductive argument on the pair $(…
Compact Lambert Type Operators Between Two l^p Spaces
Yousef Estaremi, Mohammadreza Jabbarzadeh
In this paper we investigate compactness of weighted Lambert type operators between two Lp spaces
Some Banach algebra structures for l^p(β) and their operators
Y. Estaremi, M. T. Karaev, M. R. Jabbarzadeh
In this paper we consider the generalized Duhamel product ~ on l^p(β) and characterize some Banach algebra structures for l^p(β).
