Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science .

Learning Seminar in Algebraic Combinatorics: The totally nonnegative Grassmannian is a ball George H. Seelinger. Throughout the semester, we have explored some aspects of polytopes and other spaces that exhibit a positive geometry. One space that we have seen is a positive geometry is the totally nonnegative Grassmannian, but it is not a polytope.
