On conditions for the nonperturbative equivalence of ultraviolet cut-off and dimensional regularization schemes
Ayse Kizilersu, Tom Sizer, Anthony G. Williams
We consider procedures through which an ultraviolet cut-off regularization scheme can be modified to reproduce the same results for nonperturbative renormalized Green's functions a…

Analytic Form of the One-loop Vertex and of the Two-loop Fermion Propagator in 3-Dimensional Massless QED
A. Bashir, A. Kizilersu, M. R. Pennington
We evaluate the analytic expression for the one-loop fermion-boson vertex in massless QED3 in an arbitrary covariant gauge. The result is written in terms of elementary functions o…
