Title: (Non)commutative integrable systems and Catalan numbers
Abstract: will discuss connections of Catalan numbers with solutions of some systems of differential equations over (non)commutive algebras.
Joint work with Ilia Gaiur and Vladimir Rubtsov
Title: Continuous parking sequences
Abstract:We introduce the notion of continuous parking sequences as a continuous analogue of parking functions. We allow the cars to have different lengths and the street to be longer
than the sum of the lengths of the cars. We determine the volume of the set of continuous parking sequences. Furthermore, we study the distribution where the first car, respectively, the last car would like to park. Joint work with Richard Ehrenborg and Stephan Wagner.
Title: Guessing with little data
Abstract: Automated guessing is a very popular tool in experimental mathematics. Given the first few terms of an infinite sequence, it tries to find a recurrence that the sequence is in some way likely to satisfy. If the sequence under consideration indeed satisfies a recurrence and a sufficient number of initial terms is supplied as input, then the method is bound to find the correct answer. But sufficiently many initial terms are not always available. Together with Christoph Koutschan, we have proposed a variant of the classical method that needs fewer terms and catches some of these cases. We will explain the idea behind this variant and present some conjectures that have been found with the method.
