We express the mirror map in terms of Frobenius transformation on p-adic cohomology . We discuss a $p$-adic interpretation of the conjecture about integrality of Gopakumar-Vafa invariants.13 pages,new section about Gopakumar-Vafa invariants added, some additions in the last section, some correctionsHigh Energy Physics - TheoryAlgebraic GeometryNumber Theorytext
