A method for solving nonlinear differential equations: An application to λϕ4 model
(2015-01-01)
Recently, it has been great interest in the development of methods for solving nonlinear differential equations directly. Here, it is shown an algorithm based on Padé approximants for solving nonlinear partial differential ...

SOME COMMENTS ON QUASI-INTEGRABILITY
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
In this paper we present our preliminary results which suggest that some field theory models are `almost` integrable; i.e. they possess a large number of `almost` conserved quantities. First we demonstrate this, in some ...
