Thank you, kind anon.

i have been enlightened by this magnificent proof

>(10x+x) is not 11x

i messed up a lot of that, i'm still learning a lot of this stuff myself
here

>F:A -> Set
should be F:C->Set

>F(A,Y)
should be Hom(A,Y)

by proper set i just meant set, i don't think "proper set" is mathematically any different from "set"
this clarification was needed because some categories are too "large" for their collection of morphisms to be a set, or in the case of enriched category, we explicitly replace the hom-sets with other objects that sometimes aren't sets

why are you trying to learn the yoneda lemma, if you don't mind me asking?
i figured you were an undergrad taking abstract algebra or something, but if you're not, you should definitely brush up on algebra before bothering with something as algebraic as the yoneda lemma
i certainly don't mean to discourage though

Thanks for redpilling me. I will begin spreading the word.

IT ALL MAKES SENSE NOW

a friend gave me this problem, which i read and immediately discarded
but now i'm interested in it and trying to pose it better

you have two particles A and B in 3-toroidal space (product of 3 circles)
the only force acting upon them is (classical/newtonian) gravity
solve the two-body problem

the metric messes up because d(X,X) takes on all integer values, which is what i've been trying to work around
thoughts?
