Abstract
Let p be a prime number and M the extension field of a p-adic field K obtained
by adjoining all p-power roots of all elements of K. In this paper, we show that
there exists a constant C, depending only on K and an integer g>0, which satisfies
the following property: If A/K is a g-dimensional CM abelian variety,
then the order of the torsion subgroup of A(M) is bounded by C.
