Brezis functional analysis exercise 3.17
WebThe obvious way to go about solving this exercise is to define a measure $\lambda$ on $(X, \scr{N})$ by $\lambda(E) = \int_E f d\mu$. Then $\lambda <\!\!< \nu$. So if $\nu$ is assumed to be $\sigma$-finite , one may apply the Radon-Nikodym theorem in the form of Exercise 3.14, which I quote here, to obtain the desired result (using Exercise 3. ...
