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, differential topology, geometric group theory, and general topology and continua theory.


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.


Proposals for conferences, workshops, summer/winter schools, and similar activities must be submitted through the program solicitation "Conferences and Workshops in the Mathematical Sciences" (link below) and list Topology as the program of interest. Principal Investigators should carefully read the solicitation and relevant sections of the PAPPG to obtain important information regarding the substance of such proposals and note the additional requirements for travel support requests for international events.

For these types of proposals with budgets not exceeding $50,000, which in accordance with NSF policy can be reviewed internally at NSF, the following target dates are in effect: For events that will take place between March and August in a given year, proposals should be submitted in September of the previous year. For events that will occur between September in a given year and the last day of February in the following year, the proposal should be submitted in April prior.

Proposals with budget requests that exceed $50,000 are likely to require external review, and hence are subject to longer processing time. These should be submitted roughly seven months before the event is scheduled to take place.
