The Lagrangian Ceresa Cycle

This lecture titled "The Lagrangian Ceresa Cycle" features speaker Alexia Corradini from the University of Cambridge as part of the Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar. Explore how the Ceresa cycle from algebraic geometry, known for being one of the first examples of a nullhomologous cycle that is not algebraically trivial, has a mirror counterpart in symplectic geometry. Learn about the Lagrangian Ceresa cycle, a nullhomologous Lagrangian that exists in a symplectic six-torus, and discover the new equivalence relation on Lagrangians called algebraic Lagrangian cobordism that was inspired by algebraic equivalence. The 25-minute presentation scheduled for April 11, 2025, bridges concepts between algebraic and symplectic geometry.
