Puiseux's theorem states that the local branches of a complex algebraic curve admit convergent Puiseux
expansions. If
is a nonzero polynomial with polynomial
degree
in
,
each local solution near
can be written

where
is a positive integer and
is an integer. The series
converges for sufficiently small nonzero
on a chosen branch of
(McMullen 2026, pp. 44-45).
Thus, after
,
a branch with finite limit
has a power
series parametrization

Branches tending to infinity have a Laurent series with finitely many negative powers instead.
