- 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).

This PR only splits the file `AlgebraicTopology.SimplicialSet.Basic` by creating three new files `StdSimplex`, `Boundary`, `Horn`. This prepares for a refactor and future developments of API for these simplicial sets. For example, the boundary and the horn should be redefined (keeping the defeq) as subcomplexes of the standard simplex using the `Subpresheaf` API, see #20840.

…21090) Some new API is introduced for subcomplexes of the standard simplex: any `S : Finset (Fin (n + 1))` defines a subcomplex `face S` of `Δ[n]`, and this face is isomorphic to `Δ[m]` when `Fin (m + 1) ≃o S`. Then, boundaries and horns are redefined as subcomplexes of the standard simplex and it is shown that they are unions of certain codimension one faces of the standard simplex. - [x] depends on: #21543 - [x] depends on: #21540 - [x] depends on: #21542 - [x] depends on: #21303 - [x] depends on: #21047 - [x] depends on: #20840 - [x] depends on: #21096 Co-authored-by: Joël Riou <37772949+joelriou@users.noreply.github.com>

The type of subpresheaves of a given presheaf of sets is a complete lattice.
The
large-importwarning can be ignored because it is only related to the import of the definition of what a complete lattice is.
