Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Equivariant techniques in Chromatic homotopy theory
色度 同伦理论 等变技术
2023/5/15
Chromatic homotopy theory uses the algebraic geometry of smooth 1-parameter formal groups to separate stable homotopy theory into periodic layers. The 1st layer recovers the image of Adams’ J homomorp...
