You are right. Maybe it is possible to find continuous representation for such mappinngs. In your example $\phi$ has the continuous representation.

comment Black Scholes PDE
It would be better to formulate the second part as another question (not in comments). It is kind a rule of this site.

The idea is "try and error". You also should change boundary condition: $V_1(S,T) = SV'_S(S,T) = Sf'(S)$

comment Relations among notions of convergence
1) It is not a good idea ask another question in comments. 2) Where have you find the notation $plim$ probability limits?

comment Black Scholes PDE
Why do you think that $V_1(S,t)=S\frac{\partial V(S,t)}{\partial S}$ satisfies equation?

Is it possible to find function (in form of combination elementary functions) from its fourier coefficients ?
