    In this paper, we prove there exist at least n+12+1 geometrically distinct closed characteristics on every compact convex hypersurface Σ in R2n, where n≥2. In particular, this gives a new proof in the case n=3 to a long standing conjecture in Hamiltonian analysis. Moreover, there exist at least n2+1 geometrically distinct non-hyperbolic closed characteristics on Σ provided the number of geometrically distinct closed characteristics on Σ is finite.
