Moduli theory, stability of fibrations and optimal symplectic connections


Abstract: I will describe a new notion of stability associated to 
fibrations in algebraic geometry. Much like Tian-Donaldson's notion of 
K-stability, there is an associated notion of a "canonical metric", in 
the form of an "optimal symplectic connection". Our main result shows 
that the existence of an optimal symplectic connection implies that the 
fibration is semistable. There is an associated moduli problem for 
stable fibrations over a fixed base, and I will also explain certain 
aspects of this. This is joint work with Lars Sektnan.
