Some results on Landau poles and Feynman diagram cut structure by Hopf algebra
William Dallaway, Karen Yeats
We investigate a system of differential equations for the beta function of massless scalar theory and continue the combinatorial investigation of the cut structure of Feynman…
Sequences of Trees and Higher-Order Renormalization Group Equations
William T. Dugan, Loïc Foissy, Karen Yeats
We define a notion of higher order renormalization group equation and investigate when a sequence of trees satisfies such an equation. In the strongest sense, the sequence of trees…
Completing the completion conjecture for
Simone Hu, Karen Yeats
The -invariant is an arithmetic graph invariant useful for understanding Feynman periods. Brown and Schnetz conjectured that the -invariant has a particular symmetry know…
A result on the invariant for powers of primes
Maria S. Esipova, Karen Yeats
The invariant is an arithmetic graph invariant related to quantum field theory. We give a relation modulo between the invariant at and the invariant at $p…
