Exact and semiclassical approach to a class of singular integral operators arising in fluid mechanics and quantum field theory
V. A. Fateev, R. De Pietri, E. Onofri
A class of singular integral operators, encompassing two physically relevant cases arising in perturbative QCD and in classical fluid dynamics, is presented and analyzed. It is sho…

An eigenvalue problem related to the non-linear sigma-model: analytical and numerical results
V. A. Fateev, E. Onofri
An eigenvalue problem relevant for non-linear sigma model with singular metric is considered. We prove the existence of a non-degenerate pure point spectrum for all finite values o…
