Schreiber Schreiber

This is the personal area of Urs Schreiber within the nLab. Here I am keeping material related to my research, teaching and the work of my students, see the links below. For more general information about myself see instead my main home page.

Research

I am working on a circle of ideas that goes by the name

• differential cohomology in a cohesive topos

See there for survey, introduction, details and further links. Expositions, talk notes and lecture notes are listed here. For a list of published articles and of preprints on the subject see at subprojects.
