Intermediate Value Theorem for Analytic Functions on a Levi-Civita Field

Martin Berz and Khodr Shamseddine

Full-text: Open access


The proof of the intermediate value theorem for power series on a Levi-Civita field will be presented. After reviewing convergence criteria for power series [19], we review their analytical properties [18]. Then we state and prove the intermediate value theorem for a large class of functions that are given locally by power series and contain all the continuations of real power series: using iteration, we construct a sequence that converges strongly to a point at which the intermediate value will be assumed.
