  1. what exactly is an isomorphism? - Mathematics Stack Exchange

    Aug 4, 2021 · An isomorphism within a partial order is an equality. If there is an isomorphism between two objects, then they are totally indistinguishable from the perspective of category …

  2. What is the difference between homomorphism and isomorphism?

    Isomorphism is a bijective homomorphism. I see that isomorphism is more than homomorphism, but I don't really understand its power. When we hear about bijection, the first thing that comes …

  3. terminology - What does "isomorphic" mean in linear algebra ...

    An isomorphism is a homomorphism that can be reversed; that is, an invertible homomorphism. So a vector space isomorphism is an invertible linear transformation.

  4. linear algebra - Difference between epimorphism, isomorphism ...

    30 Can somebody please explain me the difference between linear transformations such as epimorphism, isomorphism, endomorphism or automorphism? I would appreciate if somebody …

  5. Difference between "≈", "≃", and "≅" - Mathematics Stack Exchange

    The symbol ≅ is used for isomorphism of objects of a category, and in particular for isomorphism of categories (which are objects of CAT). The symbol ≃ is used for equivalence of categories. …

  6. basic difference between canonical isomorphism and isomorphims

    Apr 26, 2019 · What is the basic difference between canonical isomorphism and isomorphims? I need some basic analysis. As far as I consider on canonical isomorphism means a similarity …

  7. What are useful tricks for determining whether groups are …

    15 Proving that two groups are isomorphic is a provably hard problem, in the sense that the group isomorphism problem is undecidable. Thus there is literally no general algorithm for proving …

  8. Bijective vs Isomorphism - Mathematics Stack Exchange

    Apr 15, 2020 · Another difference between "bijective" and "isomorphism" is that bijective is an adjective but isomorphism is a noun. It would be better to ask "bijective v isomorphic" or …

  9. When is a bijective homomorphism an isomorphism?

    Jun 20, 2019 · For some "structures" (in informal sense for a lack of a formal term) in mathematics, such as groups, rings, and vector spaces, a bijective homomorphism is an …

  10. What is a natural isomorphism? - Mathematics Stack Exchange

    It's also natural in the technical sense: there is a natural transformation $\eta$ from the identity functor to the double-dual functor $ (-)^ {**}$, and the component $\eta_V : V \to V^ {**}$ of …
