Among them are the following: (i) E has the Dunford-Pettis property and any Dunford-Pettis subset of F is relatively compact; (ii) all weakly null sequences of E are limited and F has the Gelʹfand-Phillips property. These results complement similar ones by M. González and J. M. Gutiérrez del Alamo [Arch. Math. (Basel) 63 (1994), no. 2, 145–151;Glasgow Math. J. 37 (1995), no. 2, 211–219;]. It is also shown that complete continuity of all polynomials in the Taylor expansion at a of a holomorphic function f does not imply the complete continuity of f, but that such a condition is equivalent to the "local'' complete continuity of f at a: Whenever a sequence (xn) converges weakly to a and ∥xn−a∥≤c<r for all n (here r is the radius of uniform convergence of f at a), then f(xn) is norm-convergent.journal articlehttps://doi.org/10.1080/16073606.1997.9631856http://www.tandfonline.com/metadata only access517.553PolynomialCompletely continuousLocal complete continuity of holomorphic functionsFunciones (Matemáticas)1202 Análisis y Análisis Funcional
