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.

Regards,

If:

1. A is A

2. A is not not-A

does it imply that

1. B is B

2. B is not not-B
