What are...Borcherds-Kac-Moody algebras?
Goal.
I would like to tell you a bit about my favorite theorems, ideas or concepts in mathematics and why I like them so much.
This time.
What are...Borcherds-Kac-Moody algebras? Or: Still emerging from matrices.
Disclaimer.
Nobody is perfect, and I might have said something silly. If there is any doubt, then please check the references.
