So it seems the first function is properly defined since for any value x,y the function always returns a distinct pair of integers. I'm confused as to how i would prove it is a bijection. Can i just compute the inverse to prove it (since any function with an inver...
So what's a functor F:BG→BHF:BG→BH? It's precisely a group homomorphism from GG to HH! So in this example, a functor is just a function (which happens to be compatible with the group structure). But what if the domain/codomain of a functor has more than one object in...
The unit η:idSet→UFη:idSet→UF of this adjunction is a natural transformation consisting of a function ηB:B→UFBηB:B→UFB for each set BB. This function simply includes the set BB into the underlying set of the vector space FBFB. For example, if BB is the three-element set {...
Therefore, if f : A → B is a bijection function, then f-1: B → A such that f ( x ) = y ⇔ f-1( y ) = x Functions that have inverse are called one-to-one functions. Algorithm to Find the Inverse of a Function
I recently came across this question on MathOverflow asking if there are any polynomials of two variables with rational coefficients, such that the map is a bijection. The answer to this question is almost surely “no”, but it is remarkable how hard this problem resists any attempt at rigorou...

A finitary permutation of A is defined as a bijection of A generated by composing finitely many transpositions, i.e., a bijection of A leaving invariant all but finitely many elements of A. The set of all finitary permutations of A is denoted by S A 𝑆𝐴. Considering a ZF set X, ...

More precisely, he sketches a proof of the following theorem: For every set , there is a natural bijection between the proportion spaces on and the equivalence classes of torsors on . (See Baker’s post for details on how equivalence of torsors is defined.) Unfortunately, this theorem ...
