I) Static Observation is given by variables X,Y,Z,… that are maps from Ω to sets E(X), E(Y), … On Ω are given probability laws, P,Q,… Here Ω is finite, of cardinality r, thus P is given by numbers p₁, p₂, …,pᵣ positive of sum 1, a point in the simplex Δ(Ω) of dimension r-1.

Information co-cohomology Consider functions

Theorem: H is the generator of H¹ Remark: Kullback distance is also a non-zero co-homology class D(X;P,Q), with one variable but two laws

Example of tree problem, and of MaxEnt Variables Values

Constraints

III) Extension to Quantum Observation

Th: it is the generator of H¹
