Integrable discretization of recursion operators and unified bilinear forms to soliton hierarchies

Xingbiao Hu, Guofu Yu, Yingnan Zhang

In this paper, we give a procedure for discretizing recursion operators by utilizing unified bilinear forms within integrable hierarchies. To illustrate this approach, we present u…

Symmetric abstract hypergeometric polynomials

Satoshi Tsujimoto, Luc Vinet, Guo-Fu Yu +1

Consider an abstract operator $L$ which acts on monomials $x^{n}$ according to $L x^{n} = λ_{n} x^{n} + ν_{n} x^{n - 2}$ for $λ_{n}$ and $ν_{n}$ some coefficients. Let $P_{n} (x)$ be eigenpolynomials…
