introduction
- borrowed from Andrews-Gordon identity
- quantum dimension and there recurrence relation
\(d_i=\frac{\sin \frac{(i+1)\pi}{k+2}}{\sin \frac{\pi}{k+2}}}\) satisfies
\(d_i^2=1+d_{i-1}d_{i+1}\) where \(d_0=1\), \(d_k=1\)
- (*choose k for c (2,k+2) minimal model*)k := 11
d[k_, i_] := Sin[(i + 1) Pi/(k + 2)]/Sin[Pi/(k + 2)]
Table[{i, d[k, i]}, {i, 1, k}] // TableForm
Table[{i, N[(d[k, i])^2 - (1 + d[k, i - 1]*d[k, i + 1]), 10]}, {i, 1,
k}] // TableForm - Plot[d[k, i], {i, 0, 2 k}]
cyclotomic numbers
- Gauss sums
- character tables of finite groups
- values of Lie group characters at elements of finite order
- quantum dimensions in RCFT
- matrix entries in the modular group representation coming from rational VOAs
- index of subfactors ?
- 원분다항식(cyclotomic polynomial)
chebyshev polynomials
- 체비셰프 다항식
- http://mathworld.wolfram.com/ChebyshevPolynomialoftheSecondKind.html
also obey the interesting determinant identity
