## Cohomology of measurable sets

About the cohomology of measurable sets in a probability space equipped with an automorphism.

About the cohomology of measurable sets in a probability space equipped with an automorphism.

One of the attempts to quantize space without losing too much symmetry is ergodic theory. Much of my thesis belongs to this program. It is a flavor of quantum calculus, as “no limits” are involved. The story is closely related to Jacob Feldman, one of my heroes of my graduate …
