WebLike many things in mathematics, once the theory was developed, people found uses for it. Group theory is quite useful in areas of Cryptography and in Physics, just to name a couple. Group theory is essentially a study of symmetry. For many mathematical object, you want to know what type of symmetry does it has. WebAbout this book. This book is about relations between three different areas of mathematics and theoretical computer science: combinatorial group theory, cryptography, and complexity theory. It is explored how non-commutative (infinite) groups, which are typically studied in combinatorial group theory, can be used in public key cryptography.
