It is common to poles of order greater than 1 can also be considered ramification points.
2.
The ramification points are the images of talk ) 22 : 49, 8 June 2009 ( UTC)

Administration officials went over the major ramifications point by point, he said, but never mentioned that sentence on public-school choice.
4.
Now let us choose triangulations of " S " and " S & prime; " with vertices at the branch and ramification points, respectively, and use these to compute the Euler characteristics.
5.
However, the inverse of a holomorphic function in the neighborhood of a ramification point does not properly exist, and so one is forced to define it in a multiple-valued sense as a global analytic function.
6.
The topological recursion is then a recursive definition of infinite sequences of symmetric meromorphic n-forms \ omega _ { g, n } on \ Sigma ^ n, with poles at ramification points only, for integers ge " 0 such that 2g-2 + n > 0.
7.
In this way the cases " n " = 2 " g " + 1 and 2 " g " + 2 can be unified, since we might as well use an automorphism of the projective line to move any ramification point away from infinity.
