The Ceresa cycle of a curve is a 1-cycle in its Jacobian; it provided one of the first examples of a cycle which is homologically, but not algebraically trivial. I will propose an equivalence relation on Lagrangians in a symplectic manifold “mirror” to algebraic equivalence, and show it captures non-trivial symplectic geometry through a Lagrangian version of the Ceresa cycle story. This is an instance in which insights from algebraic geometry are used to hint at possibly new symplectic behaviour.
