An Instructive Treatment of a Generalization of Găvruţă’s Stability Theorem

Sarajevo Journal of Mathematics
We prove several useful theorems on Hyers sequences and their pointwise limits in quite natural ways which make a straightforward generalization of Găvruţă''s stability theorem rather plausible.   2000 Mathematics Subject Classification.

A Class of Functional Equations (Almost) Characterizing Polynomials on Integral Domains

Sarajevo Journal of Mathematics
Let $R$ be an infinite integral domain not of characteristic 2. For a given $ n\geq 2$, suppose functions $f:R\rightarrow R$ and $h:R \rightarrow R$ satisfy\begin{equation*}[x_1,x_2,\ldots,x_n;f]=h(x_1+\cdots+x_n)\prod_{j>i}(x_j-x_i),\end{equation*}where
