Important Information for Proposers

A revised version of the NSF Proposal & Award Policies & Procedures Guide (PAPPG) (NSF 22-1), is effective for proposals submitted, or due, on or after October 4, 2021. Please be advised that, depending on the specified due date, the guidelines contained in NSF 22-1 may apply to proposals submitted in response to this funding opportunity.


Supports research on algebraic topology, including homotopy theory, ordinary and extraordinary homology and cohomology, cobordism theory, and K-theory; topological manifolds and cell complexes, fiberings, knots, and links; differential topology and actions of groups of transformations; geometric group theory; and general topology and continua theory.


Principal Investigators should carefully read the program solicitation "Conferences and Workshops in the Mathematical Sciences" (link below) to obtain important information regarding the substance of proposals for conferences, workshops, summer/winter schools, and similar activities. 

Target dates for this type of proposals are currently waived in view of the ongoing pandemic concerns. Proposals for in-person meetings with budget requests not exceeding $50,000 should be submitted at least four months in advance of the meeting dates. A conference proposal with a budget request exceeding $50,000 should be submitted at least eight months before the event is scheduled to take place, in order to allow time for external review. No awards will be made to support in-person events until it is established whether any pandemic-related travel restrictions for the conference site and time frame will be in place.
