A note on "exotic integrals"

We consider Bernoulli measures $\mu_p$ on the interval $[0,1]$. For the standard Lebesgue measure the digits $0$ and $1$ in the binary representation of real numbers appear with an equal probability $1/2$. For the Bernoulli measures, the digits $0$ and $1$ appear with probabilities $p$ and $1-p$, respectively. We provide explicit expressions for various $\mu_p$-integrals. In particular, integrals of polynomials are expressed in terms of the determinants of special Hessenberg matrices, which, in turn, are constructed from the Pascal matrices of binomial coefficients. This allows us to find closed-form expressions for the Fourier coefficients of $\mu_p$ in the Legendre polynomial basis. At the same time, the trigonometric Fourier coefficients are values of some special entire function, which admits an explicit infinite product expansion and satisfies interesting properties, including connections with the Stirling numbers and the polylogarithm.Comment: In September 2021, I submitted the article to a journal where Prof. Strichartz was one of the editors. Unfortunately, he passed away in December 2021. Yesterday, in April 2022, the main editor of the journal decided to withdraw my submission because no one is able to support it at the moment. Update: new interesting formulas and connections with the polylogarithm added to version 2 and
