Category Theory

Definitions

1. A branch of mathematics that studies structures and the relationships between them at a highly abstract level, using concepts such as objects, morphisms, functors, and natural transformations. In software development, category theory influences parts of type systems, functional programming, and reasoning about composition, though it is often applied more as inspiration than as formal proof work.

   In plain English: A very abstract area of math that influences some advanced programming ideas about composition and structure.

   Example: "The talk used category theory to explain why the team's data pipelines could be refactored more safely when transformations were composed with clearer algebraic structure."
