Finding an approximate region containing all the zeros of analytic
polynomials is a well-studied problem. But the numb er of the zeros and regions
containing all the zeros of complex-valued harmonic polynomials is relatively a
fresh research area. It is well known that all the zeros of analytic trinomials
are enclosed in some annular sectors that take into account the magnitude of
the coefficients. Following Kennedy and Dehmer, we provide the zero inclusion
regions of all the zeros of complex-valued harmonic polynomials in general, and
in particular, we bound all the zeros of some families of harmonic trinomials
in a certain annular region.Comment: 8 page
