In Ann. of Math. 121 (1985), 111-168, Coleman defines p-adic Abelian integr
als on curves. Given a family of curves X/S, a differential omega and two s
ections s and t, one can define a function lambda (omega) on S by lambda (o
mega)(P)=integral (t)((P))(s)((P))omega (P). In this paper, we prove that l
ambda (omega) is locally analytic on S.
