Harry Altman at the University of Michigan

My name is Harry Altman. I recently graduated from the University of Chicago, and am currently studying mathematics at the University of Michigan. I mostly know algebra and combinatorics, but recently I've done some work on integer complexity with Joshua Zelinsky. Jeffrey Lagarias is my advisor.

Most recent updates:
2014 January 8 -- Minimum and maximum possible scores in Space Alert
2013 December 29 -- Two more words for the Co-files.
2013 October 11 -- Integer Complexity and Well-Ordering is now on arXiv!
2013 May 8 -- Added various images.

I can be reached via email at . (If you can't see my email address, that's because it's been Javascript-obfuscated to fool spammers, but you can deduce it from this page's URL.) My PGP public key can be found here.

Papers and drafts

Polished drafts, should be readable

Nothing to go here at the moment.

Old drafts, may be incomprehensible and out of date

"Problem dump"

Informal bloggy writing on problems I don't necessarily know much of anything about.

Other stuff

Here are miscellaneous files I wish to put in public view:

Here are some drawings that people have given me which I have bothered to scan:

And here are some assorted other images.
