We prove the following characterization theorem: If any three of the following four matroid invariants-the number of points, the number of lines, the coefficient of Ξ» n-2 in the characteristic polynomial, and the number of three-element dependent sets-of a rank-n combinatorial geometry (or simple ma

We study the deep interplay between geometry of quadrics in d-dimensional space and the dynamics of related integrable billiard systems. Various generalizations of Poncelet theorem are reviewed. The corresponding analytic conditions of Cayley's type are derived giving the full description of periodi
