**Categories and Modules**

by Takahiro Kato

**Publisher**: viXra.org 2015**Number of pages**: 323

**Description**:

Modules (also known as profunctors or distributors) and morphisms among them subsume categories and functors and provide more general and abstract framework to explore the theory of structures. In this book we generalize and redevelop the basic notions and results of category theory using this framework of modules.
