Ordinal logic

Ordinal logic is a branch of mathematical logic that deals with ordinal numbers and their properties, particularly within the context of set theory, model theory, and the foundations of mathematics. It often involves the use of ordinal numbers as a way to describe types of well-orderings or to analyze the structure of various mathematical objects. In more detail, ordinal numbers extend the concept of natural numbers and provide a way to generalize and analyze sequences and orderings.
