Further results on $p$-adic semigroup of contractions

Abstract

Let $E$ be an ultrametric Banach space over ${\mathbb{C}}_p.$ In this note, we obtain a new necessary and sufficient conditions on the resolvent of $A$ such that for each $m\in \mathbb{N},\Vert A^m\Vert \le 1.$

There are many errors in the based results so all the results are false
