Kalman's conjecture refers to a proposition concerning convex polyhedra and their duals in the realm of geometric combinatorics. Specifically, it deals with the possible configurations of vertices in d-dimensional convex polytopes. More precisely, the conjecture speculates about the relationship between the vertices of a convex polytope and the faces of its dual polytope.
