If there is an isomorphism between two objects, then they are totally indistinguishable from the perspective of category theory.Fri, 03 Apr 2026 10:52:00 GMThttps://math.stackexchange.com/questions/731724/what-is-the-difference-between-homomorphism-and-isomorphismIsomorphism 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 to mind is topological homeomorphism, but here we are talking about algebraic structures, and topological spaces are not algebraic structures.Thu, 02 Apr 2026 12:26:00 GMThttps://math.stackexchange.com/questions/1510769/difference-between-epimorphism-isomorphism-endomorphism-and-automorphism-withCan somebody please explain me the difference between linear transformations such as epimorphism, isomorphism, endomorphism or automorphism? I would appreciate if somebody can explain the idea with examples or guide to some good source to clear the concept.Sat, 04 Apr 2026 10:58:00 GMThttps://math.stackexchange.com/questions/5009135/questions-on-isomorphism-of-graphsI think testing isomorphism between two graphs can be done by just checking their connectivity without the use of labels. However, the definition of isomorphism as a map between two sets forces me to think that elements in each set need to be distinguishable by some use of label. Otherwise, how do we express which one is being mapped to which?Sat, 04 Apr 2026 13:00:00 GMThttps://math.stackexchange.com/questions/1650460/whats-an-isomorphismTo expand a bit on what @BrianO said, isomorphisms differ between different kinds of objects. Broadly speaking, isomorphisms preserve "structure" between objects, but what this "structure" is depends very much on whether you are talking about groups, vector spaces, algebras, etc. Hence it's difficult to say what properties are preserved in general by isomorphisms.Thu, 02 Apr 2026 22:56:00 GMThttps://math.stackexchange.com/questions/864606/difference-between-%E2%89%88-%E2%89%83-and-%E2%89%85The 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. At least, this is the convention used in this book and by most category theorists, although it is far from universal in mathematics at large.Fri, 03 Apr 2026 14:41:00 GMThttps://math.stackexchange.com/questions/5127875/isomorphic-groups-beyond-the-isomorphism-is-this-also-true-for-homomorphism2 Each isomorphism has an inverse, which is also an isomorphism between the groups. So yes: "being isomorphic" goes beyond the isomorphism in that strict sense. What we mean when we say two things in mathematics, not just group theory, are isomorphic is that the algebraic structure remains the same up to a relabelling of all the constituent parts.Sun, 22 Mar 2026 13:15:00 GMThttps://math.stackexchange.com/questions/3203028/basic-difference-between-canonical-isomorphism-and-isomorphimsWhat 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 between two geometric objectThu, 02 Apr 2026 22:28:00 GMThttps://math.stackexchange.com/questions/1201900/what-is-an-isomorphism-linear-algebraAn isomorphism is a bijective homomorphism. "Structure" can mean many different things, but in the context of linear algebra, almost exclusively means the vectorial structure -- i.e. all those rules about addition and scalar multiplication.Tue, 10 Mar 2026 21:36:00 GMThttps://math.stackexchange.com/questions/1252081/what-does-it-mean-for-something-to-hold-up-to-isomorphism4 The following is a very general discussion of the idea of an isomorphism without going into detail about what types of structures we are talking about (e.g., groups, rings, vector spaces, etc.) since the general idea should be the same across each of these. What does it mean for two structures to be isomorphic to each other?Fri, 03 Apr 2026 19:28:00 GMT
