摘要

In this paper, the discrete mKdV lattice is solved by using the modified Jacobian elliptic function expansion method. As a consequence, abundant families of Jacobian elliptic function solutions are obtained. When the modulus m → 1, these periodic solutions degenerate to the corresponding solitary wave solutions, including bell-type and kinktype excitations.
