• #### Vector bundles on degenerations of elliptic curves and Yang-Baxter equations ﻿

[OWP-2007-04] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-22)
In this paper we introduce the notion of a gemetric associative r-matrix attached to a genus one fibration with a section and irreducible fibres. It allows us to study degenerations of solutions of the classical Yang-Baxter ...
• #### Zeta functions of 3-dimensional p-adic Lie algebras ﻿

[OWP-2007-10] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-26)
We give an explicit formula for the subalgebra zeta function of a general 3-dimensional Lie algebra over the $p$-adic integers $\mathbb{Z}_p$. To this end, we associate to such a Lie algebra a ternary quadratic form over ...
