comment Necessary condition for the integral equation $u(x) = f(x)+\lambda\int K(x,t)u(t)dt$ to have a continuous solution?
Under appropriate conditions on $K$, the series will converge to a unique continuous solution for sufficiently small $|\lambda|$. It may not converge for all $\lambda$, and there may be $\lambda$ for which there is no solution or a nonunique solution.

comment Is $H(f)={1\over x} \int_0^x f(t)dt$ compact?
@GEdgar: That $f$ is not continuous at $0$. What is your point?

comment analytic functions defined on $A\cup D$
$A$ being a connected open set, if $fg = 0$ there one of the two must be $0$ on all of $A$. Same for $D$. But $A \cup D$ is not connected, so what happens on $A$ does not influence what happens on $D$. You could have, say, $f = 0$ on $A$ but not $D$, $g = 0$ on $D$ but not $A$.
