Growth estimates for Dyson-Schwinger equations
Karen Yeats
Dyson-Schwinger equations are integral equations in quantum field theory that describe the Green functions of a theory and mirror the recursive decomposition of Feynman diagrams in…
Unbounded regions of Infinitely Logconcave Sequences
David Uminsky, Karen Yeats
We study the properties of a logconcavity operator on a symmetric, unimodal subset of finite sequences. In doing so we are able to prove that there is a large unbounded region in t…
Recursion and growth estimates in renormalizable quantum field theory
Dirk Kreimer, Karen Yeats
In this paper we show that there is a Lipatov bound for the radius of convergence for superficially divergent one-particle irreducible Green functions in a renormalizable quantum f…
Admissible Dirichlet Series
Stanley Burris, Karen Yeats
We propose a definition of "Admissible Dirichlet Series" as the analog of Hayman's 1956 definition of "Admissible Power Series".
