Nekrasov-Okounkov hook length formula

introduction

• expansion formula for the powers of the Euler Product in terms of partition hook lengths, discovered by Nekrasov and Okounkov in their study of the Seiberg-Witten Theory

\[ \prod_{n=1}^{\infty}(1-x^n)^{\beta-1}=\sum_n\sum_{\lambda \vdash n}\sum_{v\in H(\lambda)}(1-\frac{\beta}{h_v^2})x^{|\lambda|} \] \(h_v\) is the hook of the box \(v\) in the Young tableau of \(\lambda\).
