The end results of a compatible family embed #
The second clause of [Kol07, 34.1], [Wlo09, Theorem 2.0.3, (4)] and [Wlo09, Theorem 3.5.1, (2)],
per open: for U₁ ≤ U₂ relatively compact, the end result of a compatible family's value on U₁
sits inside the end result of its value on U₂. The value on U₁ is the value on U₂ pulled
back along the open inclusion with the empty blow-ups erased (CompatibleFamily.compat), so the
last stages are identified by the last-stage transport of the erasure (eraseEmptyLast,
stageOfEq) followed by the last-stage lift of the inclusion (pullbackLiftLast). This module
builds the embedding CompatibleFamily.endResultEmbedding; its properties (an open embedding
onto the preimage of U₁, over M, functorial) are proved in
Hironaka.Resolution.Analytic.Functor.EndResultEmbeddingLemmas and feed the direct limit of the
end results (Hironaka.Resolution.Analytic.Functor.LimitFamily).
The
embedding of the end result over U₁ into the end result over U₂ for U₁ ≤ U₂ — the last-stage
transport of the erasure identity compat (stageOfEq), the inverse of the erasure's last-stage
isomorphism (eraseEmptyLast), then the last-stage lift of the open inclusion U₁ ⊆ U₂
(pullbackLiftLast). Its properties (an open embedding onto the preimage of U₁, over M,
functorial) are proved in Hironaka.Resolution.Analytic.Functor.EndResultEmbeddingLemmas.
