Title: Orthogonal decompositions and beyond 
Abstract: I'll explain a simple characterisation of functions
of bounded variation (as in joint work with Brezis, Seeger and Van Schaftingen) and
contrast it with an almost characterization using wavelet coefficients.  Time
permitting, I'll also describe some other ways in which the familiar notion of
orthogonality can be generalised and illustrate them with applications.
