To achieve this, we discuss the classical thermodynamics of homogeneous multicomponent media and rela...")

The intersection points of the astroida and the ellipse are used to study the case when the given point is on the ellipse. The problem is then gener...")

Since the latter have been intensively studied in the matrix or, more general, non-abelian case, examples of non-abelian Painlevé equations arise. We will discuss the problem of classifying such equations. This talk is based on a series of pa...")
