Topology

Funds algebraic and geometric topology β€” homotopy theory, K-theory, knots, manifolds, quantum field theories and topological data analysis.

OpenNational Science FoundationUnited States

NSF's Topology programme funds a wide slice of the field.

On the algebraic side: chromatic, equivariant, motivic and both stable and unstable homotopy; homology and cohomology theories; bordism and K-theory. On the geometric side: topological manifolds, knots and links, geometric topology, differential topology and transformation groups. And a set of areas that sit between topology and other fiel…
