Web17 apr. 2024 · 6.3: Injections, Surjections, and Bijections. Functions are frequently used in mathematics to define and describe certain relationships between sets and other mathematical objects. In addition, functions can be used to impose certain mathematical structures on sets. WebHomological support is tested against the pure injective objects EB. However, we show it is equivalent to test on any indecomposable pure injective E ∈Def⊗(EB). Lemma 4.15. Let B∈Spch(Tc), and let E be an indecomposable pure injective in Def⊗(EB). Then for any A ∈Tc, we have Hom(A,EB) = 0 if and only if Hom(A,E) = 0. Proof. The set
