Chern--Simons perturbation theory is one of the ways to extract topological invariants of 3-manifolds
from Chern--Simons gauge theory.
In the theory, topological invariants are given by integrations of differential forms associated with trivalent graphs.
After reviewing mainly Bott--Cattaneo and Cattaneo--Shimizu’s works which are variants of the theory,
I will explain our results which state that the latter invariants can be defined using only trivalent graphs without self-loops.
This talk is based on joint work with Bingxiao Liu.
