Linked cluster expansions beyond nearest neighbour interactions: convergence and graph classes
A. Pordt, T. Reisz
We generalize the technique of linked cluster expansions on hypercubic lattices to actions that couple fields at lattice sites which are not nearest neighbours. We show that in thi…

Hierarchical renormalization goup fixed points
A. Pordt
Hierarchical renormalization group transformations are related to non-associative algebras. Non-trivial infrared fixed points are shown to be solutions of polynomial equations. At…

Nonassociative Algebras and Nonperturbative Field Theory for Hierarchical Models
A. Pordt, C. Wieczerkowski
Hierarchical renormalization group (RG) transformations are related to nonassociative algebras. These algebras serve as a new basic tool for a rigorous treatment of global RG flows…
