Fall 2008 I was the TA for a MASS
course taught by Yakov Pesin under the title
"Elements of Fractal Geometry and Dynamics".
From that experience was born a set of course
notes, which after some extensive polishing and
reworking was published in book form by the American
Mathematical Society. Those notes are here, and the
resulting book (which is much more polished than the
rough notes) is available from the AMS
and from Amazon.
