Abstract: Generalizing several previous results in the literature on rational harmonic functions, we derive bounds on the maximum number of zeros of functions $$f(z) = \frac{p(z)}{q(z)} - \overline{z}$$f(z)=p(z)q(z)-z¯, which depend on both $$\mathrm{deg}(p)$$deg(p) and $$\mathrm{deg}(q)$$deg(q). Furthermore,… read more here.
