On the relation between the dual AKP equation and an equation by King and Schief, and its N-soliton solution

Peter H. van der Kamp, Da-jun Zhang, G. R. W. Quispel

The Dual of the lattice AKP (DAKP) equation [P.H. van der Kamp et al., J. Phys. A 51, 365202 (2018)] is equivalent to a 14-point equation related to the lattice BKP equation, found…

Recurrence relations for the generalized Laguerre and Charlier orthogonal polynomials and discrete PainlevÃ© equations on the $D_{6}^{(1)}$ Sakai surface

Xing Li, Anton Dzhamay, Galina Filipuk +1

This paper concerns the discrete version of the PainlevÃ© identification problem, i.e., how to recognize a certain recurrence relation as a discrete PainlevÃ© equation. Often some…
