apparent boundaries of projective varieties

abstract:

fix a smooth projective variety in projective space and project it to a linear subspace of the same dimension. the ramification divisor of this projection is classically known as the ``apparent boundary''. how does the apparent boundary move when we move the center of projection? i will discuss the geometry arising from this natural question. i will explain why the situation is most interesting for varieties of minimal degree, and how it is related to limit linear series for vector bundles.
