**Introduction to Renormalisation**

by Joao F. Melo

**Publisher**: arXiv 2019**Number of pages**: 68

**Description**:

These are introductory lecture notes aimed at beginning graduate students covering fundamental concepts and ideas behind the renormalisation group. Our main goal is to motivate it and then explore its consequences, in the context of quantum field theory. We shall reproduce the standard results without needing any mention of cancellation of infinities.
