N-Algebraic Structures and S-N-Algebraic Structures
  For the first time, we have introduced the concept of N-groups, N-semigroups, N-loops, and N-groupoids. We also define a mixed N-algebraic structure. The main aim of this book is to attract young mathematicians to this interesting field. It contains more than 200 new definitions. These concepts find applications in fields like finite automaton, coloring problems and coding theory.
