The Erdős Center runs programs in two Semesters. Spring Semester runs from January to June, and Fall Semester runs from August to December. See erdoscenter.renyi.hu for running and planned Semesters. A proposal for a Semester Program should be written in such a way that the members of the Scientific Advisory Board get a clear picture of the state of the art and the aims of the program. The Institute is open for all areas of mathematics. Deadline: May 4, 2025
