Description
We analyze the low lying spectrum of SU(N) gauge theories on a 2-dimensional spatial torus in a singular large N limit obtained by sending the rank of the group to infinity while shrinking the size of the torus to zero. The absence of tachyonic instabilities along the process leads to constraints on the possible values of N and the magnetic flux on the torus, singling out a limiting sequence constructed out of Fibonacci numbers. We will discuss the implications of this observation for non-commutative gauge theory and volume reduction.
