Commentationes Mathematicae

Commentationes Mathematicae (Prace Matematyczne) is an international journal for mathematical research. Its main area of interest includes functional analysis, operator theory, approximation theory, differential and functional equations, theory o real functions, measure and integration theory, theory of complex functions and analytic number theory. However, outstanding papers from other areas of mathematics are also considered for publication.
