- The
relativevalue is the weighted sum of the differences with weight given by the inverse of the current value of the statistic. - The
absolutevalue is therelativevalue divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).
…ommunity#42947) The existence of invariant probability measures for continuous maps on compact spaces. Co-authored-by: Lua Viana Reis <me@lua.blog.br>

…ply and Subrepresentation.quotient (leanprover-community#41081) Add a lemma for `Subrepresentation` recording the inherited group action. Help avoid unfolding `Subrepresentation.toRepresentation` when analyzing the action. Add the `quotient` representation associated to a `Subrepresentation`. It wraps up `Representation.quotient` and `Representation.Subrepresentation` and then we also record the inherited group action.

…43814) This PR removes many uses of `to_additive existing`. Many of these used to be necessary, but are now not anymore thanks to various improvements to `to_additive`.
…rmations (leanprover-community#43847) On the suggestion of @sgouezel, formulate the First Main Theorem of Value Distribution Theory as a statement on the invariance of the characteristic function under postcomposition with automorphisms of the projective line. Historically, this formulation is probably due to Georges Valiron.
The `upload_cache` job uploads a second copy of its staged set to R2, for the `master` container only. This PR extends it to `forks`.
The cache tool does not change. The `forks` upload passes `--container=forks` and sets `MATHLIB_CACHE_PUT_BASE_URL` to the developer bucket. The tool writes the container's layout under the bucket, `mathlib4-forks/f/{repo}/{sha}/{hash}.ltar` with the marker `mathlib4-forks/m/{repo}/{sha}`, the same paths the Azure container holds. `master` keeps its flat write to `MATHLIB_CACHE_R2_PUT_URL`. The bucket URL comes from a new secret, `MATHLIB_CACHE_R2_DEVELOPER_PUT_BASE_URL`.
