Abstract

Let ω\omega denote an area form on S2S^2. Consider the closed symplectic 4-manifold M=(S2×S2,Aωaω)M=(S^2\times S^2, A\omega \oplus a \omega) with 0<a<A0<a<A. We show that there are families of displaceable Lagrangian tori L0,x,L1,xML_{0,x},\, L_{1,x} \subset M, for x[0,1]x \in [0,1], such that the two-component link L0,xL1,xL_{0,x} \cup L_{1,x} is non-displaceable for each xx.
