Streszczenie
We study the maximal number of zeros of harmonic polynomials with complex coefficients. We also study the zeros of harmonic polynomials with complex coefficients which admit a decomposition $F(z)=P_{n}(z)+\overline {Q_{m}(z)}$ where $P_{n}$ and $Q_{m}$ are polynomials of degree $n$ and $m$ (respectively), with $n \gt m$.
