@AndréNicolas yes but why does it converge despite integrand tending to infinity? I think it's like $$\int_0^1 \frac{dx}{\sqrt{x}} = \sqrt{x}\bigg|_0^1 = 1$$

comment Laplace transform on a finite interval $f(t)= \int_0^1 e^{-xt} f(x) \, dx$
@OmranKouba OK it is Laplace transform of $f(x)\mathbf{1}(x < 1)$. Using formulas from Laplace Transform Table. I am getting $(1 - e^{-t})\hat{f}(t)$ where $\hat{f}$ is the Laplace transform of $f$.

comment Minimum of $|az_x-bz_y|$
If $N_x$ and $N_y$ are very large, the minimum is the gcd.
