Compactifying spaces of branched covers

Moduli spaces of geometrically interesting objects are often non-compact. They need to be compactified by adding some degenerate objects. In many cases, this can be done in several ways, leading to a menagerie of birational models, which are related to each other in interesting ways.

Some remarks on the Postnikov tower

We will discuss a geometric approach to the Postnikov tower which admits a natural extension to the homotopy theory of schemes.

Singular special Lagrangian n-folds

Special Lagrangian n-folds are high-dimensional volume minimizing submanifolds discovered around 1982 by Harvey and Lawson in their pioneering work on calibrations. More recently special Lagrangians n-
