 A characterization of projective geometries Bull. Korean Math. Soc. 1995 Vol. 32, No. 2, 215-219 Young Jin Yoon Kunsan National University Abstract : It is known that a projective geometry $PG(n-1,q)$ is upper homogeneous, has a modular copoint, and its characteristic polynomial is $(\lambda - 1)(\lambda - q)(\lambda - q^2) \dots (\lambda - q^{n-1})$. We prove the converse of the above statement. Keywords : characteristic polynomial, upper homogeneous, modular copoint MSC numbers : 05B35 Downloads: Full-text PDF
