A remark on the motivic Galois group and the quantum coadjoint action
Harald Grosse, Karl-Georg Schlesinger
It was suggested by Kontsevich that the Grothendieck-Teichmueller group GT should act on the Duflo isomorphism of su(2) but the corresponding realization of GT turned out to be tri…
The universal envelope of the topological closed string BRST-complex
Harald Grosse, Karl-Georg Schlesinger
We construct a universal envelope for any Poisson- and Gerstenhaber algebra. While the deformation theory of Poisson algebras seems to be partially trivial, results from string- an…
The Eigenfunctions of the q-Harmonic Oscillator on the Quantum Line
Harald Grosse, Stefan Schraml
We construct a complete set of eigenfunctions of the q-deformed harmonic oscillator on the quantum line. In particular the eigenfunctions corresponding to the non-Fock part of the…
Finite Gauge Theory on Fuzzy CP^2
Harald Grosse, Harold Steinacker
We give a non-perturbative definition of U(n) gauge theory on fuzzy CP^2 as a multi-matrix model. The degrees of freedom are 8 hermitian matrices of finite size, 4 of which are tan…
The β-function in duality-covariant noncommutative ϕ^4-theory
Harald Grosse, Raimar Wulkenhaar
We compute the one-loop β-functions describing the renormalisation of the coupling constant λand the frequency parameter Ωfor the real four-dimensional duality-covariant noncommuta…
