I'm looking for a TAU professor which I attended a lecture of his during
High School. He seems to be interested in the subject I will describe
shortly, and I'd like to get in touch with him because I have made some
progress in the subject, some time after the lecture.

From what I remember his name was Amos Erlich or something similar. The
problem is that there is no such professor in the Math department of TAU.
In any case, he holds lectures and discussions about the subject in
various places in Israel (or from what he told us, in the world).

Here is a description of the subject:

Let's take the transformation i -> (2*i (mod n)). Now let's plot a graph
whose nodes are all the possible modulos for n, i.e. 0 - (n-1). Now we
explore the different shapes formed in this graph, how it is derived from
its factors, etc.

Took me exacxtly two seconds to click Search on the TAU home page and
type his name into the Google prompt. The only difference was that it
was natural to me to spell his name as Amos Ehrlich...

What is needed to get the quick Search engines available in Web sites to
use agrep-like algorithms in lieu of simple find?
agrep would have helped Shlomi find Ehrlich when he was looking for
Erlich.

How would it help?
without knowing that Erlich is spelled diffrently, you wouldn't be able to
formulate the right regexp.

No, I wouldn't. But knowing that Ehrlich could be spelled differently
but being unsure about the actual spelling, I (and Shlomi) could use
a regexp search. I miss regexps often when I search the web.

I doubt that creating a web search engine would make a successful
