摘要

In this paper, we are concerned with the problem of locating the zeros of lacunary polynomials of a quaternionic variable with restricted real and quaternionic coefficients. We derive bounds of Eneström–Kakeya type for the zeros of these polynomials by virtue of a maximum modulus theorem. Our results generalize some recently proved results about the distribution of zeros of a quaternionic polynomial.
