What does 'front evolution' mean? Is it a concept from fluid dynamics? Could someone knowledgeable provide an appropriate link please? -- Rinconsoleao ( talk) 14:03, 9 June 2008 (UTC)
I was just wondering about the uniqueness of the viscosity solution. Most PDEs can be proven to have a unique solution. What about the viscosity solution? Are they unique, or are there multiple viscosity solutions to a given PDE? (this will probably depend on the PDE in question, but some info on it would be appreciated). 131.155.59.211 ( talk) 10:03, 7 January 2010 (UTC)
In the literature (I'm just reading to understand the concept, I admit) there is also often talk about a reformulation of the definition in terms of semijets. See for instance Michael G. Crandall, Hitoshi Ishii, and Pierre-Louis Lions: User's Guide to Viscosity Solutions of Second Order Partial Differential Equations. This concept seems to have advantages for some calculations involving viscosity solutions. Would it be interesting to add a section about the definition of the semijets plus redirect to it (there's nothing found at the moment when looking for that term!) and the reformulation? I'd be willing to write it after I understand the matter sufficiently (including of course literature citations as appropriate), if this is deemed a useful addition.
