Abstract: This paper is concerned with the Hamilton-Jacobi (HJ) equations of multidimensional space variables with convex Hamiltonians.The author  proves the extreme curve in the formula of the solution to the HJ equation is a characteristic and for each point in upper half-space,there exists a valid characteristic segment passing through it.

Key words: Hamilton-Jacobi equation, characteristic, Hopf-Lax formula
