Log-Expansions from Combinatorial Dyson-Schwinger Equations
Olaf Krüger
We give a precise connection between combinatorial Dyson-Schwinger equations and log-expansions for Green's functions in quantum field theory. The latter are triangular power serie…

Vertex-Constraints in 3D Higher Spin Theories
Stefan Fredenhagen, Olaf Krüger, Karapet Mkrtchyan
We analyse the constraints imposed by gauge invariance on higher-order interactions between massless bosonic fields in three-dimensional higher-spin gravities. We show that vertice…
