Tóm tắt: The Möbius function $mu(n)$ is an important function in number theory and combinatorics. It is intimately linked with the distribution of primes. The Möbius randomness principle states that $mu$ is so random-like that it does not correlate with any bounded ``reasonable'' or ``low-complexity'' function $F$, in the sense that $sum_{nleq x}mu(n)F(n)=o(x)$. I will talk about an instance of this principle in $mathbb{F}_q[t]$ (the ring of polynomials over a finite field $mathbb{F}_q$), where $mu$ is replaced by its $mathbb{F}_q[t]$-counterpart and $F$ is a quadratic or linear phase. In the linear case our result is unconditional while in the quadratic case our result is conditional.
This is joint work with Pierre-Yves Bienvenu.
