„Numbers and the physical law: Hopf algebras, periods and infinities“
We review mathematical aspects of renormalizable quantum field theories. 
Apart from their celebrated success in comparison with experiment, there 
has been much progress recently in understanding their mathematical 
structure.  We focus on the appearance of Hopf algebras and the role of 
periods in this context.

„Graphical Algebras - A new approach to Congruence Lattices“
In 1970, H. Werner gave a characterisation of which sublattices of a 
partition lattice were actually the congruences of an algebra on the 
underlying set. In his classification, he gave a new operation on 
partition lattices, called graphical composition of relations. We 
consider the question of which lattices with a notion of graphical 
composition can be represented as congruence lattices, with graphical 
composition of relations as in Werner.
