the "zero" could be a theta. its a greek letter and its most commonly used to notate an angle in geometric stuff.
as for the M, i have no idea what you are talking about.

A vertical line is Phi, not theta, which uh.. I can't remember using Phi's for anything yet. Sorry.
Edit: Here's a Phi article I found from a google search. Hope it helps

my experience with notations is they represent whatever the prof/book want it to represent

the "curvatious" M is probably a "mu". it's a greek symbol used to represent the coefficient of friction in physics. it's used in statistics too, but i hated that class so i forgot everything i could about it right away.

a zero with a verticle line through its middle flux from physics?

it could also be a way for bad writers (my self for example) to help distinguish O's and o's from 0'.
if this is what you are talking about, then yes, it is [url=http://web.ift.uib.no/Fysisk/Teori/KURS/WRK/TeX/symALL.html]phi[/quote]
Why cant people google? (Google "Math Symbols", yeesh...) of course, i had a teacher who used it as theta, and a math teacher that used Alpha for i
so it realy depends on the person.

Vertically, not diagonally.

i believe phi can be drawn with a line that is either vertical or diagonal.
but an "o" with a diagonal line usually means "does not exist".

I believe english isn't the most universe language, and the greek letters are symbols of different notations rather than just letters alone meant for greeks to understand. But then again, people do learn these symbols for ease of representations.

The zero with the diagonal slash represents the empty set.
Phi is usually used for angles, just like theta. When two different angles are needed in one equation, often theta and phi are both used.
