Note: The assigned readings are potential sources for exam questions. I will
NOT ask narrow factual questions about these readings, but you should be
able to relate their main arguments to the material we have discussed in
class.
Note: The following outline does NOT cover everything we have studied in
the class. All concepts and applications that we have discussed in class are
possible exam topics.
Good items to study would be the class slides, the class notes, and the
solutions to the problem sets. If something seems unfamiliar, check your
notes, the posted notes, and then, if you still have questions, email me or
stop by TA office hours.
