CR Singularities of 4-manifolds in C3
Spring 2009 Central Sectional meeting of the American Mathematical Society

We consider real 4-submanifolds in complex 3-space at CR singular points, where the tangent space is a complex hyperplane. The extrinsic geometry of a submanifold near such a point is described by quantities depending on the local dening equations but invariant under holomorphic coordinate changes. I will give some concrete examples of compact manifolds embedded with the minimum possible number of non-degenerate CR singularities.
