Abstract |
Blowing-up is a fundamental process in Algebraic Geometry.
We will throw a first glance at this process by means of examples, which
are accessible to visualization. Namely, we consider the special case of
blowing-up the plane with respect to a curve. We explain
how the resulting blown-ups may be embedded into 3-space and how these
embedded blown-ups can be visualized, by means of a computer for example.
We explain a project to produce a movie obtained by letting vary the coefficients of the defining polynomials of the curve. The work presented is based on junior research peformed in the Diploma Theses of my studends Markus Brandenberg, Nadine Korolnik and Simone Koller. The lecture will be accessible to students with a modest background in calculus and linear algebra. |
