Constraints on the masses of fourth generation quarks
S. Hosseini, M. Mohammadi Najafabadi, A. Moshaii +2
We study the one-loop contribution of the down-type quark of the standard model-like fourth generation (b') on the top quark electric dipole moment. Using the known limits on the t…

Quadratic--quartic functional equations in RN--spaces
M. Eshaghi Gordji, M. Bavand Savadkouhi, C. Park
In this paper, we obtain the general solution and the stability result for the following functional equation in random normed spaces (in the sense of Sherstnev) under arbitrary …

On approximate cubic homomorphisms
M. Eshaghi Gordji, M. Bavand Savadkouhi
In this paper, we investigate the generalized Hyers--Ulam--Rassias stability of the system of functional equations $$f(xy)=f(x)f(y), \qquad\qquad. f(2x+y)+f(2x-y)=2f(x+y)+2f(x-y)+1…
