Results are obtained both in the real and the complex cases, as well as some generalizations to the nonhomogeneous case and to holomorphic functions in the complex case. Kuratowski convergence of closed sets is used in order to characterize pointwise convergence. We require uniform convergence of the distance function to get uniform convergence of the sequence of polynomials.engjournal articlehttp://www.ams.org/journals/tran/1998-350-12/S0002-9947-98-02342-3/S0002-9947-98-02342-3.pdfhttp://www.ams.org/restricted access517.986.6517.518.45Polynomials in Banach spacesSet convergenceLevel setsSequences of homogeneous polynomials on a Banach spaceAnálisis matemático1202 Análisis y Análisis Funcional
