On Gelfand and MacPherson's combinatorial formula for Pontrjagin classes

Olakunle Abawonse, Laura Anderson

Published 2022-10-30Version 1

In 1992 Gelfand and MacPherson gave a local and combinatorial formula for the Pontrjagin classes of a differential manifold. We give an expanded version of their discussion and highlight the origins of combinatorial differential manifolds in their work.
