theory

 

 

q-Pochhammer

  • partition generating function
  1. Series[1/QPochhammer[q, q], {q, 0, 100}]
  • Dedekind eta
  1. Series[QPochhammer[q, q], {q, 0, 100}]

 

 

q-hypergeometric series

\(\sum_{n\geq 0}^{\infty}\frac{q^{n^2/2}}{(q)_n}\sim \exp(\frac{\pi^2}{12t}-\frac{t}{48})\)

 

  1. f[q_] := QHypergeometricPFQ[{}, {}, q, -q^(1/2)]
    g[q_] := Exp[-(Pi^2/(12 Log[q])) + Log[q]/48]
    Table[N[f[1 - 1/10^(i)]/g[1 - 1/10^(i)], 50], {i, 1, 5}] // TableForm

 

 

KdV Hirota polynomials

  • Series[1/QPochhammer[q, q^2] - 1/QPochhammer[q^2, q^4], {q, 0, 100}]
  • KdV equation
