The harmonic function article summary states:

There also exists a seemingly weaker definition that is equivalent. Indeed a function is harmonic if and only if it is weakly harmonic.

But the weakly harmonic function article states:

This definition is weaker than the definition of harmonic function because it doesn't require that f is a twice continuously differentiable function. If it is the case, this definition is then equivalent to the definition of harmonic function.
