Abstract
Let be a simple CM abelian variety over a CM field , a rational prime. Suppose that has potentially ordinary reduction above and is self-dual with root number . Under some further conditions, we prove the generic non-vanishing of (cyclotomic) -adic heights on along anticyclotomic -extensions of . This provides evidence towards Schneider's conjecture on the non-vanishing of -adic heights. For CM elliptic curves over $\Q$, the result was previously known as a consequence of work of Bertrand, Gross--Zagier and Rohrlich in the 1980s. Our proof is based on non-vanishing results for Katz -adic -functions and a Gross--Zagier formula relating the latter to families of rational points on .
