comment Projection of a set $G_\delta$
thanks for answering! wanted to find out whether I can apply the result to prove that $\pi(f^{-1}(0,1))$ not is Borel measurable where $f=\limsup_{n\rightarrow \infty }f_n$ and $f_n: \mathbb{R}\rightarrow \mathbb{R}$ are continuous, although my teacher says that $\pi(f^{-1}(0,1))$ is Borel

Honestly a very interesting construction. It may get some explicit expression of the fields ?

There is way to generalize for $v_1,...v_k$ in $\mathbb{R}^d$ ?

This right, and in the case of $\mathbb{R}^3$ with $v_1,v_2$ as gender $v_3$ ?

true! I'm lost as to plot the phase diagram for the case $ \sqrt{x} $

thanks for the suggestions. You will have some program to plot the case $f(x)=\sqrt{x}$, it can also be $f(x)=ln(x)$ with $n=r=\alpha=0.5$ ?
