Derivatives in Vector Spaces

  • Serge Lang
Part of the Undergraduate Texts in Mathematics book series (UTM)


Let E, F be normed vector spaces. Let λ: EF be a linear map. The following two conditions on A are equivalent:
  1. (1)

    λ is continuous.

  2. (2)
    There exists C > 0 such that for all υE we have
    $$\left| {\lambda (\upsilon )} \right| \leqq C\left| \upsilon \right|$$
