“…The simplest nontrivial case corresponds to m 11 = 1, m 33 = 0 and p 33 = 1, which solve (14). Then (11) and the first equation of (13) lead to n 13 = α, n 31 = −β [1] , n 32 = −n 23 .…”
“…Then from (17), we have (Dα)(Dβ [1] ) − p 11 (1 − αβ [1] ) = p 2 1 , which gives p 11 = (1 + αβ [1] ) (Dα)(Dβ [1] ) − p 2 1 , where p 1 is a constant of integration. Summarizing above discussion, we obtain a Darboux transformation of elementary type, named as eDT.…”
In this paper, we consider a supersymmetric AKNS spectral problem. Two elementary and a binary Darboux transformations are constructed. By means of reductions, Darboux and Bäcklund transformations are given for the supersymmetric modified Korteweg-de Vries, sinh-Gordon, and nonlinear Schrödinger equations. These Darboux and Bäcklund transformations are adopted for the constructions of integrable discrete super systems, and both semidiscrete and fully discrete systems are presented. Also, the continuum limits of the relevant discrete systems are worked out.

“…These supersymmetric integrable prototypes have been extensively studied in the past four decades, and shown to have various novel features, such as fermionic nonlocal conserved densities [18], nonunique roots of Lax operator [19], and odd Hamiltonian structures [20]. Recently, discrete integrable systems on Grassmann algebras [21][22][23][24], as well as Grassmann extensions of Yang-Baxter maps [25], have been established due to the development of Darboux-Bäcklund transformations of super and/or supersymmetric integrable equations.…”
We extend the symbolic representation to the ring of N=1 supersymmetric differential polynomials, and demonstrate that operations on the ring, such as the super derivative, Fréchet derivative, and super commutator, can be carried out in the symbolic way. Using the symbolic representation, we classify scalar λ‐homogeneous N=1 supersymmetric evolutionary equations with nonzero linear term when λ>0 for arbitrary order and give a comprehensive description of all such integrable equations.
“…Nonlinear equations are very important in describe evolution phenomena in engineering and physics. People have investigated many useful methods to obtain the evolution solutions: the inverse scattering method [1][2][3], the Hirota's bilinear method [4][5][6], the Darboux and Backlund transformation [7,8]. Sine-cosine method [9,10].…”
Abstract. The discrete nonlinear evolution equation concerned is the nonlinear Ostrovsky equation, which is employed in engineering and physics to describe some nonlinear evolution phenomena such as the temperature transmission and investigated by expand function method. The novel traveling wave solutions are obtained. The results are simply discussed.
