Articles in Progress:
Finding geometry in classical number theory: the Chinese Remainder
Theorem, Kronecker's Theorem and wrapping lines around tori. Under
construction.
Perelman proves Poincaré. This is an expository paper on
the Poincaré and Geometrization Conjectures. The goal of the paper
is to lay out all of the definitions, as well as some related motivational
results and explanatory material, in a form which should be accessible to
an advanced undergraduate mathematics student (say who has had advanced
calculus and some linear and abstract algebra). The paper has been
submitted for publication.
Hash chains: a weak link in trusted computing. Undergoing
revisions, but here is a preliminary version:
Who?ogle: an associative interface to the web which preserves
individual and community privacy. In preparation, watch this space.
Hem-lines, web rankings and other correlates of the stock
market. In preparation, watch this space.
Ergodic theory and cryptography. In preparation, watch this space.
Universal Turing machines in other universes. In preparation,

a description:
NOTE: Despite extensive research, it remains unclear to me who owns the
copyright on MAFTIA deliverables -- perhaps it is some branch of the EU? --
and the MAFTIA web site does not clearly
answer this question. In cases where this could be a concern, I suggest
contancting one of the senior (former) MAFTIA organizers or perhaps the EU
Information Society and Media Directorate-General (see
this web site).
