Aims & Scope

Quaestiones Mathematicae publishes research papers from a wide range of mathematical topics which will often reflect the current mathematical research interests in South Africa; but submissions in English from anywhere in the world are welcome. Acceptance of a paper is normally determined by two independent favourable referees reports. Longer survey papers of exceptional quality are also considered from time to time.
