## Slides of some talks
Pre-beamer |

This page contains only the screen versions of talks. Instructions at the foot of the page explain how to create a printer version if you want one.

Most of these are talks at conferences or research seminars. I have highlighted in red talks which were designed for a more general audience (usually non-mathematicians, non-specialists, undergraduates, or high school students).

Apart from the last batch, theseare either the Beamer slides of the talks or versions
made with the `handout` option to Beamer, which simply ignores pauses
and produces one page per frame. My default Beamer font is Palatino, using the
`mathpazo` package.

Print versions can be produced as follows. If the output from the screen
version is called `x1.pdf`, then run `pdflatex` on the following
input file:

\documentclass[a4paper]{article} \usepackage{pdfpages} \begin{document} \includepdf[pages=1,landscape=false,frame=false,noautoscale=false]{x1.pdf} \includepdf[pages=2-last,nup=2x3,landscape=false,frame=true, noautoscale=true,scale=0.7,delta=0mm 5mm]{x1.pdf} \end{document}This puts the first slide on the front page and the others 3 rows and 2 columns per page.

Note that the filename occurs twice!

If you don't have a handout version of the slides, note the numbers of the last slide of each frame and put the list of these numbers in place of 2-last.
