A Very Elementary Proof of Prime Number Theorem
Published:
In the context below, \(p\) will denote prime numebers always.
The First Post — Jones Polynomial
Published:
The Jones polynomial via Wilson loop is essentially obtained from Cayley-Hamilton’s equation. We will work with SU(2)\(_k\) gauge group. Let the trivial loop in 2+1 spacetime of a majorana zero mode be \(d\) then
