Mission Statement
• To provide an Irish forum for the publication of good quality
research in pure and applied mathematics;
• To provide a focal point for the research interests of Irish
mathematicians and for international research related to their
interests;
• To constitute a contribution by the Royal Irish Academy
and, more generally, the island of Ireland, to promote and
develop mathematics.
Submissions
Submissions are particularly welcome from those whose work is related to that of Irish mathematicians or to the work of the members
of the Editorial Board. All submissions are refereed. E-mail submissions to Submissions@ria.ie
