The Abel Visiting Scholar Program is intended for mathematicians professionally based in developing countries to visit an international research collaborator for a period of one month. For visits that are longer than one month, applicants must provide evidence of financial support from the host institution to cover the living expenses beyond the first month.

From 2013-2025 program was designed for post doctoral mathematicians in the early stages of their professional careers to offer the opportunity for a ‘research sabbatical,’ a necessary complement to teaching and other academic duties for mathematicians desiring to also sustain a viable research program. Usually up to 3 Grants were available per year.

Since 2026 the Program is intended for graduate students based in developing countries, who have finished at least 2 years of their PhD on the date of the application deadline or immediately following their PhD completion (max. 2 years after the defense) and who are under the age of 35. Priority will be give to students having submitted at least one paper to an international peer-reviewed journal.

The Abel Visiting Scholar Program is fully funded by the Abel Prize in mathematics and is administered by the Commission for Developing Countries of the International Mathematical Union.
