I was quite surprised when it was pointed out to me that https://github.com/agda/agda-stdlib/blob/master/src/Algebra/Morphism/Structures.agda defined isomorphism in terms of injectivity and surjectivi…

Hi, I'm probably doing something wrong here, but I can't seem to find a semigroup in the database. Perhaps it is how I am testing for isomorphism? But from what I understand, these methods should work…

This is an issue for a medium to advanced level golang programmer. It also requires a strong understanding of graph algorithms and the willingness to figure out how to implement a graph isomorphism al…

The simplification_isomorphism() method in the class
sage.groups.finitely_presented.FinitelyPresentedGroup_with_category
returns an isomorphism, which would in particular mean it is invertible. It w…

I'd like to check if two lattices L_1, L_2 over a number filed are isomorphic with the restriction that the isomorphism is an automorphism group of the third lattice L_3. This can be achieved by using…
