Topology | PD 22 1267

Opportunity Information: Apply for PD 22 1267

The National Science Foundation (NSF) Topology program (Funding Opportunity Number PD 22 1267) is a discretionary research grant opportunity that supports fundamental work across a broad range of topics in topology and closely connected areas of mathematics. Its core focus is on algebraic topology, with emphasis on homotopy theory as well as both ordinary and extraordinary homology and cohomology theories. The program also explicitly includes cobordism theory and K-theory, reflecting interest in deep structural tools that connect topology to geometry, algebra, and other parts of mathematics.

Beyond algebraic topology, the opportunity covers research on topological manifolds and cell complexes, including questions about how these spaces are built, classified, and related to one another. It also welcomes work on fiberings (such as fibrations and bundles), and on low-dimensional and geometric topics like knots and links. Differential topology is within scope as well, especially where it intersects with transformation groups and the study of group actions on manifolds or other spaces. The description also highlights geometric group theory, signaling support for research at the interface of topology and group theory, including how algebraic properties of groups reflect geometric or topological structure. In addition, the program encompasses general topology and continua theory, covering more classical and foundational directions involving topological spaces, separation properties, compactness-like behavior, and the structure of continua.

In addition to standard research proposals, the NSF notes specific guidance for community events such as conferences, workshops, and summer or winter schools. Those event proposals are not submitted directly under the Topology program announcement itself; instead, they must be submitted through the separate NSF solicitation titled "Conferences and Workshops in the Mathematical Sciences," while listing "Topology" as the program of interest. Investigators are expected to follow the Proposal and Award Policies and Procedures Guide (PAPPG) and pay close attention to extra requirements that can apply to travel support, especially for international events.

The timeline guidance is most detailed for conference-style proposals at or below 50,000 dollars in requested budgets, since those may be reviewed internally at NSF. For events planned between March and August of a given year, NSF indicates proposals should be submitted in September of the previous year. For events occurring between September of a given year and the end of February of the next year, the suggested submission time is April beforehand. For event proposals requesting more than 50,000 dollars, NSF cautions that external review is more likely and processing can take longer, so they should be submitted roughly seven months before the event date to allow adequate lead time.

Key administrative details from the listing include that the funding instrument is a grant, the activity category is science and technology and other research and development, and the CFDA number is 47.049. Eligibility is listed as unrestricted, meaning the program does not impose special applicant-type restrictions in the notice itself (though standard NSF rules and the specific solicitation requirements still apply). The listing shows an original closing date of 2024-11-05, and it does not specify an award ceiling or expected number of awards in the provided data.
