Real footprints of complexification

Every real algebraic variety is enclosed in its complexification, the complex variety defined by the same equations. The complex environment generates various features which are invisible from a purely real viewpoint, and these in turn have profound effects on the behavior of the real variety. In the talk, phenomena of this kind will be discussed.
Note : this was initially planned as a Friday symplectic geometry seminar, but it is now moved to the Thursday colloquium.
