Jonathan A Poritz
Primary position, course info
• I am an Associate Professor in the Department of Mathematics and Physics at Colorado State University, Pueblo, where I am teaching in the Summer of 2012:
• Web pages for (some) past courses are here.
Here is a link to my usual daily schedule.
Random Useful Information
• Current analog contact coordinates are available here.
• E-mail: jonathan.poritz@gmail.com (That is my primary, preferred e-mail address. If something seems not to be working with it, however, you can try poritzj@post.harvard.edu or jonathan@poritz.net)
Feel free to send me encrypted e-mail, by using my GnuPG key (Fingerprint:7C8B ADBA FE03 3C31 4E52 071D 8488 65F3 7638 565E)
• In case you need to be able to recognize me, here is an image.
Here is a CV; and here are some past affiliations.
Materials for a Cryptology lab at the 2011 CSU-P MathSciFest
Random Scientific Information
• Some of my [p]reprints can be found here.
• Follow this link for some interactive mathematics -- using a Java applet to help visualize the geometry of fundamental domains (like the pattern of circles above) for the action of cyclic subgroups of $PSL(2,\CC)$ on the boundary $\partial H^3_\RR$of three-dimensional hyperbolic space.
• Many pretty fundamental domains (like the one to the left) in the interior of $H^3_\RR$ for the action just mentioned are shown in a gallery.

An explanation of the background is available for the incurably curious; other pictures on this page are fully explained in my papers -- read them or weep!
