In my opinion the DG article should be improved in several directions:
- At the moment the article does not give a mathematical description of DG methods. Short definitions of the basic ingredients such as the approximation spaces (as in the finite element article) would be helpful. Most people looking up the DG entry on Wikipedia presumably search for a specification of the method and are less interested in the names of contributors.
- The references should be carefully chosen. The article 'J. Loverich and U. Shumlak, A Discontinuous Galerkin Method for the Full Two-Fluid Plasma Model, Computer Physics Communications 169(3), 251, 2005.', which appeared in the proceedings volume of the "Europhysics Conference on Computational Physics 2004" may illustrate an area of application of DG methods but does not appear to contain fundamental results on DG methods. It does in particular not contain anything similar to a theorem or proof.
- The English in the article is not as good as it should be, in particular the last paragraph.
- Some sections are also somewhat imprecise. E.g. the two engineers mentioned are presumably Bassi and Rebay.
- Clearly, the contributions of all researchers mentioned in text body of this Wiki entry are significant. However is Wikipedia really the place to discuss their importance? Especially since many aspects of DG are still part of very active research and the long-term impact of many results is still not clear. Moreover, many other researchers who had large impact on DG are not mentioned here. Would one want to attempt to list them all here?

references to Stokes edit
- In the current page the first paper mentioned that is dealing with Stokes problem is the paper by Bassi and Rebay (the "two engineers"). It not clear that this is the first instance of DG for Stokes problem as earlier contributions have been given for example in the paper of Baker, Jureidini, Karakashian, Piecewise solenoidal vector fields and the Stokes problem. SIAM J. Numer. Anal. 27 (1990), no. 6, 1466–1485, and many other papers. Since history for DG for Stokes problem is complicated, the last paragraph was removed and replaced by a general reference the LNCSE no.11 volume on DG methods. —Preceding unsigned comment added by 81.107.85.50 (talk) 10:17, 22 May 2011 (UTC)

Is a factor in the boundary term missing? — Preceding unsigned comment added by Rostspik (talk • contribs) 05:58, 25 September 2020 (UTC)
