SUMMARY:Benjamin Bakker\, A Proof of Matsushita's Conjecture
DESCRIPTION:    Speaker\n\n\nBenjamin Bakker\nUniv. Illinois Chicago\n\n\n\n\n\n\nMatsushita conjectured that for any Lagrangian fibration f:X→B of a compact hyperkahler manifold X\, the fibers deform either maximally or trivially in moduli. In this talk I’ll explain how to prove this conjecture via Hodge theory. I will also discuss some other features of the topology of Lagrangian fibrations and a result about the density of torsion points in sections. Time permitting\, I will discuss some more recent work with C. Schnell from this perspective reproving a result of J.-M. Hwang that B is projective space if it is smooth.
