Below are Lecture Notes and Problems (with most solutions included)
for some of the lectures
Greg Gamble
has given since 1995 to the
*UWA Academy for Young Mathematicians*.
For the 2005, 2006,
2007, 2008, 2009, 2010, 2011,
2012, 2013
lectures, only PDF files are provided
(for earlier lectures I also provide DVI and PostScript formats - but
these days most visitors to this site won't know what to do with those ;-).)

If you have a machine that is operating under some variety of UNIX
then you may possibly have `xdvi` in which case you may
be able to configure your web-browser to run that as an application
on the `.dvi` links below; similarly, you may be able to
configure `ghostview` to view the `.ps` links below.
If you have a PostScript printer then downloading the `.ps`
links and printing maybe your best option.
Lastly, `Acrobat Reader` is available for most operating systems
(and might be a plug-in of your web-browser)
and can be used to read the `.pdf` links;
use the `v3.0` link if you have `Acrobat Reader v3.0`
and the `v2.1` link if you have `Acrobat Reader v2.1`.
(Later versions of Acrobat Reader seem o read the v3.0 links
perfectly well.)

If none of the `.dvi`, `.ps`, `.pdf` links
make the material below accessible to you send me an
email
explaining your problem and I'll see what I can do.
If you find a *mistake* I'd certainly like to know, also.
(Thanks to all those who have pointed out errors in the past.)

Please use the.dvi,.psorhypertextlink, if you can (where one exists), since, your browser will not render some of the text correctly if it is not capable of displaying subscripts, superscripts or tables.
