Polylogarithmic

In mathematics, a polylogarithmic function in n is a polynomial in the logarithm of n, ak(log⁡n)k+ak−1(log⁡n)k−1+⋯+a1(log⁡n)+a0.{\displaystyle a_{k}(\log n)^{k}+a_{k-1}(\log n)^{k-1}+\cdots +a_{1}(\log n)+a_{0}.}The notation logn is often used as a shorthand for (log n), analogous to sinθ for (sin θ).
