The theme of this paper is to understand the formation and behavior at these upstream\/downstream patterns from the point view of the symmetry inherent in the PDE. This paper investigates symmetry breaking and spatial oscillations in finite difference solutions for the inviscid Burgers and one-dimensional Navier\u2013Stokes shock equations using the Lax\u2013Wendroff, TVD, and nonoscillatory, nonfree parameter dissipative schemes. Symmetry breaking is considered as a candidate for the inherent cause of the nonphysical oscillations in the vicinity of the shock.<\/jats:p>","DOI":"10.1137\/050648201","type":"journal-article","created":{"date-parts":[[2008,1,23]],"date-time":"2008-01-23T18:06:49Z","timestamp":1201111609000},"page":"325-343","source":"Crossref","is-referenced-by-count":5,"title":["Lie Symmetry Preservation and Shock-Capturing Methods"],"prefix":"10.1137","volume":"46","author":[{"given":"Zheng","family":"Ran","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"351","published-online":{"date-parts":[[2008,1,23]]},"reference":[{"key":"R1","first-page":"271","volume":"47","author":"K.Godunov S.","year":"1959","journal-title":"Mat.
