Integrable boundary conditions for quad equations, open boundary reductions and integrable mappings

Vincent Caudrelier, Peter H. van der Kamp, Cheng Zhang

In the context of integrable partial difference equations on quad-graphs, we introduce the notion of open boundary reductions as a new means to construct discrete integrable mappin…

$L^{p}$ eigenfunction bounds for fractional Schrödinger operators on manifolds

Xiaoqi Huang, Yannick Sire, Cheng Zhang

This paper is dedicated to $L^{p}$ bounds on eigenfunctions of a Schödinger-type operator $(- Δ_{g})^{α /2} + V$ on closed Riemannian manifolds for critically singular potentials $V$ . The…

Eigenfunction equations of lattice KdV equations and connections to ABS lattice equations with a $δ$ term

Cheng Zhang, Haifei Zhang, Da-jun Zhang

We develop lattice eigenfunction equations of lattice KdV equation, which are equations obeyed by the auxiliary functions, or eigenfunctions, of the Lax pair of the lattice KdV equ…
