Statement T: Joint Work on Math Forum in Category Theory
During the attempt of proving Statement T, I first-handedly experienced glimpses of real research on the forum Matheplanet.
The Relevance of the Yoneda Lemma and the Importance of Examples – Part 1
We give the example of (affine) group schemes to demonstrate the importance of the Yoneda Lemma. In part 1, we discuss how basic matrix groups relate to algebras via representable functors.
Math in unconventional places
A short essay about spending time with mathematics in places that you wouldn't expect at first.
I think I am Asian.
What does it really mean to be Asian or American or German? Are you European-American? German-Asian?
A digression on categorical notions
A familiar functor from analysis, why rings should have a 1 and intuition on the equivalence of categories.
