Special conformal groups of a Riemannian manifold and Lie point symmetries of the nonlinear Poisson equation

Comments on regularization ambiguities and local gauge symmetries
(World Scientific Publ Co Pte Ltd, 2005-08-20)
We study the regularization ambiguities in an exact renormalized (1 + 1)-dimensional field theory. We show a relation between the regularization ambiguities and the coupling parameters of the theory as well as their role ...
Nonlinear self-adjointness of a 2D generalized second order evolution equation
(Pergamon-elsevier Science LtdOxfordInglaterra, 2012)
Renormalized new solutions for the massless Thirring model
(World Scientific Publ Co Pte Ltd, 2005-12-10)
We present a nonperturbative study of the (1 + 1)-dimensional massless Thirring model by using path integral methods. The regularization ambiguities - coming from the computation of the fermionic determinant - allow to ...
