In science:

Intersection points of λ with the generators aj , bj are in one-to-one correspondence with intersection points of λ with the sides aj , bj of P D g ,n and therefore with elements τ ∈ CPerm(λ) satisfying, respectively, LF(τ ) = aj and LF(τ ) = bj .
Dual generators of the fundamental group and the moduli space of flat connections
We can either assign two intersections with opposite intersection numbers to the starting point of ai or one with positive intersection number to the endpoint and one with negative intersection number to the starting point.
Dual generators of the fundamental group and the moduli space of flat connections
Again, there is an ambiguity in the graphical assignment of the intersection points of bj with itself, which can be either drawn as two intersection points at the starting point of bj or one at the starting point and one at the endpoint.
Dual generators of the fundamental group and the moduli space of flat connections
Note that in contrast to the situation for the generators aj , bj there is no ambiguity in assigning the intersection points of mi with itself since we required that one of the two intersection points lies at the starting point and one at the endpoint of mi .
Dual generators of the fundamental group and the moduli space of flat connections
In the graphical procedure the intersection points of λ with mi , aj , bj are obtained by decomposing it into its factors and removing those intersection points of the starting or endpoint of a generator mi , aj , bj which occur both on a segment tyk p and psyk+1 with opposite intersection numbers.
