Non-isotopic symplectic tori in elliptic surfaces

We construct an infinite family of homotopic but pairwise smoothly non-isotopic symplectic tori in the rational elliptic surface E(1)=P²#9P̄². Furthermore, we show that any two of these tori are smoothly equivalent, i.e., there exists an orientation-preserving self-diffeomorphism of $E(1)$ that carries one torus to the other. Our construction can be generalized for many other symplectic $4$-manifolds, for example, the logarithmic transforms E(n)ₘ for integers $n,m>1$.
