Let $\mathcal C(n,d)$ denote the Chebyshev hypersurface of degree $d$ in $\mathbb P^n$, and let $\mathcal N(n,d)$ be its set of nodes. For a finite node set $\mathcal N$, write…

Let ${\mathcal C}(n,d)$ be the Chebyshev hypersurface of degree $d$ in $\mathbb{P}^n$, where $n=2n_1$ is even. Write $ct(D)$ for the coincidence threshold of a hypersurface $D$. Co…
