Nikita,

An updated answer to your third question:

Actually not a typo, just poor editorial practice.

Using capital letters will make it plain:

(v1j, v2j,...,vLj)

The text uses a lower case "L" in the last term, which with a fairly 
good magnifying glass is different from the number "1" in the subscript 
for v at the beginning of the sequence.

Same is true for the second sequence in that equation.

That also happens in expression (12) on page 12, expressions (18), (19), 
and (20), on page 13, and expression (21) on page 14.

Note that p_m is used in (13) on page 12, despite P_M being defined as 
the set of all path expressions. In (13) it simply marks the last in a 
sequence of path expressions.

The usage of p_m is also inconsistent with p_n which you will find in 
4.2, condition #3.

There are others I am sure I have not noticed yet so please feel free to 
point them out. Consistency and good editorial practice (like not using 
graphically similar characters to mean different things) would go a long 
way to making the formalism easier to read.

Sorry 'bout that!

Hope you are having a great day!

Patrick
