Query: The mixability of elliptical distributions with supermodular functions   The concept of $\phi$-complete mixability and $\phi$-joint mixability was
first introduced in Bignozzi and Puccetti (2015), which is a direct extension
of complete and joint mixability. Following Bignozzi and Puccetti (2015), we
consider two cases of $\phi$ and investigate the $\phi$-joint mixability for
elliptical distributions and logarithmic elliptical distributions. We obtain a
necessary and sufficient condition for the $\phi$-joint mixability of some
distributions and a sufficient condition for uniqueness of the center of
$\phi$-joint mixability for some elliptical distributions.
