I will not be lecturing this course in 2013/14.
Instead, a course with this title will be given by Karen Vogtmann.
The content may change.
Please check the official course pages for further information.
Group presentations. Cayley graphs. Quasi-isometries. (Fundamental groups and hyperbolic geometry.) Hyperbolic groups. Isoperimetric inequalities. [Other topics depending on time and demand.]
100% written examination.
These are the 2010 versions, as handed out in lectures.
Part 1 Supplement to Section 6 (word problem).
Part 2 First part of Section 7 (isoperimetric stuff).
Part 3 Second part of Section 7.

Several accounts were written around shorly after Gromov's paper. There's been no systematic general introduction since (for some reason).

See also the notes by Short et al, and by Bowditch (me) in the
Trieste notes above.
A truncated icosidodecahedron (The Cayley graph of the isosahedral group after collapsing double edges.)
Hyperbolic planar tessellations by Don Hatch (celebrated composer of Manfred the murderer).
A tessellation of hyperbolic 3-space by right-angled regular dodecaheda. This isn't quite the same the one you get from Seifert-Weber space. That one has five dodecahedra meeting around each edge rather than four.
