Controlled K-frames in Hilbert Spaces
Asghar Rahimi, Shahram Najafzadeh, Mohamad Nouri
K-frames were recently introduced by L. Gǎvruta in Hilbert spaces to study atomic systems with respect to bounded linear operator. Also controlled frames have been recently introdu…

Stability of the Jensen--type functional equation in ternary Banach algebras: An alternative fixed point approach
A. Ebadian, Sh. Najafzadeh
Using fixed point methods, we prove the generalized Hyers--Ulam--Rassias stability of ternary homomorphisms, and ternary multipliers in ternary Banach algebras for the Jensen--type…
