Summary Summary.: For a group $(G,\cdot) $ and a real or complex inner product space
$(E,\langle\cdot,\cdot\rangle) $ with norm $\def\lr {[\!]}\lr.\lr $ we consider the functional …

In this paper, we investigate the additive rho-functional inequalities parallel to f (Sigma (k)(j=
1) xj)-Sigma (k)(j= 1) f (xj) parallel to˂= parallel to rho (kf (Sigma (k)(j= 1) xj/k)-Sigma (k)(j= 1) …

In this paper, we solve the additive rho-functional inequalities parallel to f (x+ y)-f (x)-f (y)
parallel to˂= parallel to rho (2f (x+ y/2)-f (x)-f (y)) parallel to parallel to 2f (x+ y)/2)-f (x)-f (y) …

In this paper, we solve the additive functional equations and where s is a fixed nonzero
complex number. Furthermore, we prove the Hyers–Ulam stability of the additive functional …

Beginning around the year 1980, the topic of approximate homomorphisms and derivations
and their stability theory in the field of functional equations and inequalities was taken up by …
