Stability of the general quintic functional equation

International Journal of Mathematical Analysis, 2021
The general quintic functional equation is a generalization of many functional equations such as the additive, the general quadratic, the general cubic, and the general quartic functional equation.

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.

Remark on the Second Bounded Cohomology of Amalgamated Product of Groups

Sarajevo Journal of Mathematics
For any cardinal number ${\mathcal M}$ we construct examples of amalgamated products and HNN extensions of groups such that the dimension of the space of second bounded cohomologies is at least ${\mathcal M}$.
