### Abstracts:

 Rectifiable measures, Raanan Schul.  When does a (locally) finite Borel measure $\mu$ on $R^n$ give full measure to a countable family of Lipschitz images of $R$? We discuss the question, interesting examples and known results.  We will distinguish between two special cases: $\mu$ is absolutely continuous with respect to the 1-dimensional Hausdorff measure  $H^1$, vs. $\mu$ is singular with respect to $H^1$. We will only assume first year graduate measure theory.
