I'm not necessarily looking for an explicit homeomorphism, just an Jul 1, 2016 · A homework problem asked to find a short exact sequence of abelian groups $$0 \rightarrow A \longrightarrow B \longrightarrow C \rightarrow 0$$ such that $B \cong A \oplus C$ although the sequence does not split. (In advanced geometry, it means one is the image of the other under a mapping known as an "isometry", which provides a formal definition of what "same shape and size" means) Two congruent triangles look exactly the same, but they are not the In mathematical notation, what are the usage differences between the various approximately-equal signs "≈", "≃", and "≅"? The Unicode standard lists all of them inside the Mathematical Operators B This approach uses the chinese remainder lemma and it illustrates the "unique factorization of ideals" into products of powers of maximal ideals in Dedekind domains: It follows $-1 \cong 10-1 \cong 9$ hence you get a well defined map $$\phi: \mathbb {Z} [i] \rightarrow B$$ by defining $\phi (a+bi):=a+3b$. In geometry, $\cong$ means congruence of figures, which means the figures have the same shape and size. Feb 10, 2025 · Let $R$ be a ring with unity, and let $e$ be an idempotent element of $R$ such that $e^2 = e$. Jul 15, 2024 · Proving that $imf \cong A^ {\sim}$ in the context of universal properties. If $e$ is a central idempotent of $R$, then we obtain the following ring isomorphism: $$ R/ReR \cong ( Sep 28, 2024 · Claim: $\operatorname {Hom}_ {G} (V,W) \cong \operatorname {Hom}_ {G} (\mathbf {1},V^ {*} \otimes W)$ I'm looking for hints as to how to approach the proof of this claim.
