Quadratic embedding constants of path graphs
Wojciech Młotkowski
We characterize positive definiteness for some family of matrices. As an application we derive explicit value of the quadratic embedding constants of the path graphs.

The free Meixner class for pairs of measures
Michael Anshelevich, Wojciech Młotkowski
We investigate in more detail the two-state free convolution semigroups of pairs of measures whose Jacobi parameters are linear in the convolution parameter . These semigroups w…
