Title: Category of type respecting embeddings and the amalgamation property

Abstract

Proofs of upper bounds on big Ramsey degrees always works with special 
embeddings that are derived from subtrees of tree of types. I will 
discuss a stand-alone definition of these embeddings and discuss some of 
their properties, in particular a variant of amalgamation property which 
is often a key lemma needed to characterise the big Ramsey degrees.
