  • Abstract

    The optimization problem that lies at the heart of the computer proof for Property (T) satisfies strong duality. The dual problem has a geometric interpretation similar to Property (FH). We explain this and show how the geometric picture can be used to simplify the problem and prove Property (T) for Aut(F_4).
