Analogues of Harglotz-Zagier-Novikov function

Recently, Choie and Kumar extensively studied the Herglotz-Zagier-Novikov function $\mathfrak{F}(z;u,v)$, defined as \begin{align*} \mathfrak{F}(z;u,v) = \int_{0}^{1} \frac{\log(1-ut^z)}{v^{-1}-t} dt, \quad $\text{for}$ \quad \mathfrak{Re}(z)>0. \end{align*} They obtained two-term, three-term and six-term functional equations for $\mathfrak{F}(z;u,v)$ and also evaluated special values in terms of di-logarithmic functions. Motivated from their work, we study the following two integrals, \begin{align*} \mathfrak{F}(z;u,v,w) &=\int_{0}^1 \frac{\log(1-ut^z)\log(1-wt^z)}{v^{-1}-t}$\text{d}$t, \ \mathfrak{F}k(z;u,v) &= \int{0}^{1} \frac{\log^k(1-ut^z)}{v^{-1}-t} , $\text{d}$t, \end{align*} for $\mathfrak{R}\mathfrak{e}(z)>0$ and $k\in \mathbb{N}$. For $k=1$, the integral ${\mathfrak{F}}_k(z;u,v)$ reduces to $\mathfrak{F}(z;u,v)$. This allows us to recover the properties of $\mathfrak{F}(z;u,v)$ by studying the properties of ${\mathfrak{F}}_k(z;u,v)$. We evaluate special values of these two functions in terms of poly-logarithmic functions.
