Some Algebraic Structure on Figurate Numbers

Some Algebraic Structure on Figurate Numbers

In this study, some information about figurate numbers and centered polygonal numbers are given. Also, a general binary operator that includes all centered polygonal numbers is defined and it is investigated whether the algebraic structures defined with the general binary operator specify a groupoid and semigroup or not. And finally, some examples are given on the subject.
