I will speak about $\varepsilon $-independence, which an interpolation of classical and free independence originally studied by M$ł{}$otkowski and later by Speicher and Wysoczanski. To be $\varepsilon $-independent, a family of algebras in particular must satisfy pairwise classical or free independence relations prescribed by a {0,1}-matrix $\varepsilon $, as well as more complicated higher order relations. I will discuss how matrix models for this independence may be constructed in a suitably-chosen tensor product of matrix algebras. This is joint work with Benoit Collins.
