What are examples of symmetric copulas $f(x,y)=f(y,x)$ having relative minima for $f(x,x)$?

In a previous posting on this site RepulsiveBehavior I attempted to detail a quantum-information-theoretic separability/entanglement problem I am pursuing. Detailed issues of sampling sizes for a data …

Is a bivariate copula relevant in this physics setting manifesting uniform univariate margin...

By the symmetry as Bloch radii variables between a3 and b3, we know such independence also holds for b3. So, the probability of separability is uniform over both a3 and b3 $\in [0,1]$. …
