WebIn mathematics, Friedrichs's inequality is a theorem of functional analysis, due to Kurt Friedrichs.It places a bound on the L p norm of a function using L p bounds on the weak derivatives of the function and the geometry of the domain, and can be used to show that certain norms on Sobolev spaces are equivalent. Friedrichs's inequality generalizes …

I'v learnt some proofs about this inequality like the application of normed-equivalence theorem, but yesterday I find another proof which I think is strange (using Bramble-Hilbert).
