It has been shown that the algebraic and topological study of automata theory played a key role in the development of fundamentals of computer science. This book demonstrates some algebraic and topological aspects of rough automata and fuzzy automata. Specifically, this text present the foundations of algebraic theory of rough automata which will attract the researchers and will help in finding some successful applications of rough automata theory. Ideas for future research and explorations are also provided. Students and researchers in computer science and mathematics will benefit from this work.
