Joint complete monotonicity of rational functions in two variables and toral $m$-isometric pairs

Akash Anand, Sameer Chavan, Rajkamal Nailwal

We discuss the problem of classifying polynomials $p:{\mathbb{R}}_{+}^2\to (0,\infty )$ for which $\frac{1}{p}=\{\frac{1}{p(m,n)}{\}}_{m,n\ge 0}$ is joint completely monoto…
