I did state though that all second derivatives of u would
have L^p norms bounded by that of the Laplacian. Kleinermann asked me for
an elementary explanation of this, but I couldn't think of one.
I haven't the foggiest idea of what an "elementary explanation" of anything during a math graduate degree committee assessment would even sound like.

- teraflop 3y ago"Elementary" is a somewhat subjective term that roughly means "from first principles", i.e. not relying on a bunch of advanced theorems and concepts. It doesn't necessarily mean the explanation is simple or concise.
- eru 3y agoOften the advanced theorems and concepts make for a simpler and more concise explanation. I guess the closest equivalent in programming is "implement X without using any external libraries (or perhaps only the standard library)".
