This textbook offers an creation to uncomplicated class concept, with the purpose of creating what could be a complicated and occasionally overwhelming topic extra obtainable.  In writing approximately this difficult topic, the writer has delivered to undergo all the adventure he has won in authoring over 30 books in university-level mathematics.
The objective of this e-book is to give the 5 significant rules of type concept: different types, functors, usual modifications, universality, and adjoints in as pleasant and comfortable a fashion as attainable whereas while no longer sacrificing rigor. those themes are built in an easy, step by step demeanour and are observed by way of quite a few examples and workouts, so much of that are drawn from summary algebra. 
The first bankruptcy of the booklet introduces the definitions of class and functor and discusses diagrams,
duality, preliminary and terminal items, designated kinds of morphisms, and a few specific different types of categories,
particularly comma different types and hom-set different types.  Chapter 2 is dedicated to functors and natural
transformations, concluding with Yoneda's lemma.  Chapter three provides the idea that of universality and bankruptcy four maintains this dialogue via exploring cones, limits, and the commonest express structures – items, equalizers, pullbacks and exponentials (along with their twin constructions).  The bankruptcy concludes with a theorem at the lifestyles of limits.  Finally, bankruptcy five covers adjoints and adjunctions.
Graduate and complex undergraduates scholars in arithmetic, laptop technological know-how, physics, or similar fields who want to know or use class conception of their paintings will locate An creation to class Theory to be a concise and obtainable source.  It should be quite worthwhile for these searching for a extra ordinary therapy of the subject earlier than tackling extra complicated texts.
