TITLE: Integration of the Classical Action for the Quartic Oscillator in 1 + 1 Dimensions
AUTHORS: Robert L. Anderson
KEYWORDS: Action; Integral
JOURNAL NAME: Applied Mathematics, Vol.4 No.10C, October 23, 2013
ABSTRACT: In this paper, we derive an explicit form in terms of end-point data in space-time for the classical action, i.e. integration of the Lagrangian along an extremal, for the nonlinear quartic oscillator evaluated on extremals.
