I'm currently reviewing an academic paper written by a non-native English writer. The paper has an introductory section titled "Foundations" which contains definitions of later used terminology as well as short summaries of relevant subjects.
Does "Foundations" appropriately describe such a section? I was under the impression that it's mostly used to mean either a part of a building or the "assumed common" knowledge of a whole science branch ("foundations of mathematics" for example). I've seen such sections being titled for example as "Background". Would that be more appropriate?
