A positive integer without small prime factors. This means that all prime factors of $n$ must be greater than $\mathcal P(n)$, where $\mathcal P(n)$ is a function that increases more slowly than $n$. For example,

$$\mathcal P(n)=n^{1/(\ln\ln n)^2}.$$

Quasi-prime numbers are well distributed in arithmetic progressions with large modulus.
