Relational Mathematics

SYMMETRY AND GEOMETRY. One of the core concepts essential to understanding natural phenomena and the dynamics of social systems is the concept of “relation”. Furthermore, scientists rely on relational structures with high levels of symmetry because of their optimal behavior and highperformance. Humanfriendships, socialandinterconnectionnetworks, trafficsystems, chemical structures, etc., can beexpressed asrelational structures. A mathematical model capturing the essence of this situation is a combinatorial object exhibiting a high level of symmetry, and the underlying mathematical discipline is algebraic combinatorics—the most vivid expression of the concept of symmetry in discrete mathematics.
