Category of sets

In mathematics, a "category of sets" refers to a framework where sets (groups of objects) and the functions (rules or mappings) between them are studied collectively. Essentially, it focuses on how different sets relate through functions, emphasizing the structure and relationships rather than individual elements. This approach allows mathematicians to analyze and understand concepts like functions, transformations, and relationships in a unified way across all sets, facilitating deeper insights into mathematical structures and their properties.
