Germ of a function at a filter

The germ of a function f : α → β at a filter l : Filter α is the equivalence class of f with respect to the equivalence relation EventuallyEq l: f ≈ g means ∀ᶠ x in l, f x = g x.

Main definitions

We define

• Filter.Germ l β to be the space of germs of functions α → β at a filter l : Filter α;
• coercion from α → β to Germ l β: (f : Germ l β) is the germ of f : α → β at l : Filter α; this coercion is declared as CoeTC;
• (const l c : Germ l β) is the germ of the constant function fun x : α ↦ c at a filter l;
• coercion from β to Germ l β: (↑c : Germ l β) is the germ of the constant function fun x : α ↦ c at a filter l; this coercion is declared as CoeTC;
• map (F : β → γ) (f : Germ l β) to be the composition of a function F and a germ f;
• map₂ (F : β → γ → δ) (f : Germ l β) (g : Germ l γ) to be the germ of fun x ↦ F (f x) (g x) at l;
• f.Tendsto lb: we say that a germ f : Germ l β tends to a filter lb if its representatives tend to lb along l;
• f.compTendsto g hg and f.compTendsto' g hg: given f : Germ l β and a function g : γ → α (resp., a germ g : Germ lc α), if g tends to l along lc, then the composition f ∘ g is a well-defined germ at lc;
• Germ.liftPred, Germ.liftRel: lift a predicate or a relation to the space of germs: (f : Germ l β).liftPred p means ∀ᶠ x in l, p (f x), and similarly for a relation.

We also define map (F : β → γ) : Germ l β → Germ l γ sending each germ f to F ∘ f.

For each of the following structures we prove that if β has this structure, then so does Germ l β:

• one-operation algebraic structures up to CommGroup;
• MulZeroClass, Distrib, Semiring, CommSemiring, Ring, CommRing;
• MulAction, DistribMulAction, Module;
• Preorder, PartialOrder, and Lattice structures, as well as BoundedOrder;
• OrderedCancelCommMonoid and OrderedCancelAddCommMonoid.
