Left $θ$ -derivations on weighted convolution algebras

M. Eisaei, M. J. Mehdipour, Gh. R. Moghimi

Let $θ$ be a homomorphism on $L_{0}^{\infty} (R^{+}, ω)^{*}$ . In this paper, we study left $θ$ -derivations on $L_{0}^{\infty} (R^{+}, ω)^{*}$ . We show that every left $θ$ -derivation on…

On scalable $K$ -frames and a version of Lax-Milgram theorem

F. Javadi, M. J. Mehdipour

In this paper, we first prove a theorem by a little modification on the Lax-Milgram theorem. Then, using $K$ -frames, we obtain lower and upper bounds for the results obtained from…

On the Phase Retrievable Sequences

F. Javadi, M. J. Mehdipour

In this paper, we study phase retrievable sequences and give a characterization of phase retrievability of a sequence of bounded linear operators on a Hilbert space $H$ ; in particu…

On $g -$ Fusion Frames Representations via Linear Operators

S. Jahedi, F. Javadi, M. J. Mehdipour

Let ${M_{k}}_{k \in Z}$ be a sequence of closed subspaces of Hilbert space $H$ , and let ${Θ_{k}}_{k \in Z}$ be a sequence of linear operators from $H$ …

Jordan derivations on the $θ -$ Lau products of Banach algebras

M. Ghasemi, M. J. Mehdipour

In this paper, we study Jordan derivation-like maps on the $θ -$ Lau products of algebras. We characterize them and prove that under certain condition any Jordan derivation-like maps…

Products of generalized derivations on rings

S. R. Behresi, M. J. Mehdipour

In this paper, we show that if the product $(D_{1} D_{2}, d_{1} d_{2})$ of generalized derivations $(D_{1}, d_{1})$ and $(D_{2}, d_{2})$ on an algebra $A$ is a generalized derivation, then $d_{1} D_{2}$ …
