Introduction to a small cancellation theorem
Confluentes Mathematici, Tome 13 (2021) no. 1, pp. 79-102.

This note is intended as an introduction to two previous works respectively by Dahmani, Guirardel, Osin, and by Cantat, Lamy. We give two proofs of a Small Cancellation Theorem for groups acting on a simplicial tree. We discuss the application to the group of plane polynomial automorphisms over any ground field.
