What it funds

Official synopsis as published by the agency, formatted for readability.

The Topology program supports research on algebraic topology, including chromatic, equivariant, motivic, and (un)stable homotopy, homology and cohomology theories; bordism and K-theory; topological manifolds; knots and links; geometric topology; differential topology; transformation groups; topological quantum field theories; contact and symplectic structures; infinity and model categories; and topological data analysis.

Conferences

Topology proposals for conferences, workshops, summer/winter schools, and similar activities must be submitted to PD 22-1267 using the "Conference" or “Travel” proposal type in research.gov.

The program’ssubmission windows for conference/travel proposalsare September 1-30 and April 1-30. Proposals with budgets not exceeding $50,000 should be submitted during a submission window that occursat least six months prior to the event. Proposals with budget requests that exceed $50,000 should be submitted during a submission window that occursat least eight months prior to the event.
