Determinant Bounds and the Matsubara UV Problem of Many-Fermion Systems
Walter Pedra, Manfred Salmhofer
It is known that perturbation theory converges in fermionic field theory at weak coupling if the interaction and the covariance are summable and if certain determinants arising in…

Singular Fermi Surfaces II. The Two--Dimensional Case
Joel Feldman, Manfred Salmhofer
We consider many--fermion systems with singular Fermi surfaces, which contain Van Hove points where the gradient of the band function vanishes. In a previous paper…

Singular Fermi Surfaces I. General Power Counting and Higher Dimensional Cases
Joel Feldman, Manfred Salmhofer
We prove regularity properties of the self-energy, to all orders in perturbation theory, for systems with singular Fermi surfaces which contain Van Hove points where the gradient o…
