How wrong is this intuition? I mean, do most weak derivatives coincide with piecewise derivatives?

here differentiable means in a weak sense?
Nis-Erik Bohne
01:13:34
Question: if u' and u'' weakly exist dose this also imply that u'' is the weak differental of u'?
Loris Pedrelli/Buck
01:13:35
Ok thanks
Nis-Erik Bohne

thank you

Why is ^2 inside?
Loris Pedrelli/Buck
01:23:44
just the partial derivative?
Bogdan Raonic
01:23:47
Partial derivative?
Loris Pedrelli/Buck
01:23:50
in direction i
Loris Pedrelli/Buck
01:25:46
The norm of the gradient
Bogdan Raonic
01:30:26
No
Loris Pedrelli/Buck
01:30:41
Nope
Loris Pedrelli/Buck
01:30:56
A constant u
Bogdan Raonic
01:30:59
Take a constant function
Bogdan Raonic
01:35:19
Which are not in Lp?
Nis-Erik Bohne
01:35:24
functions that go to infinity at the boundary
Loris Pedrelli/Buck
01:35:26
the non integrable ones?
Bogdan Raonic
01:35:27
Or whose derivatives are not in Lp
