Trace identities from identities for determinants

Stephen Humphries, Christian Krattenthaler

We present new identities for determinants of matrices $(A_{i, j})$ with entries $A_{i, j}$ equal to $a_{i, j}$ or $a_{i, 0} a_{0, j} - a_{i, j}$ , where the $a_{i, j}$ 's are indeterminates.…

Recent progress in the study of representations of integers as sums of squares

Heng Huat Chan, Christian Krattenthaler

In this article, we collect the recent results concerning the representations of integers as sums of an even number of squares that are inspired by conjectures of Kac and Wakimoto.…

Non-commutative Hopf algebra of formal diffeomorphisms

Christian Brouder, Alessandra Frabetti, Christian Krattenthaler

The subject of this paper are two Hopf algebras which are the non-commutative analogues of two different groups of formal power series. The first group is the set of invertible ser…
