Abstract: The link between the short wave model of the Camassa-Holm equation SCHE andbilinear equations of the two-dimensional Toda lattice 2DTL is clarified. Theparametric form of N-cuspon solution of the SCHE in Casorati determinant isthen given. Based on the above finding, integrable semi-discrete andfull-discrete analogues of the SCHE are constructed. The determinant solutionsof both semi-discrete and fully discrete analogues of the SCHE are alsopresented.
