Polynomial Approximation of Symmetric Functions

Markus Bachmayr, Geneviève Dusson, Christoph Ortner +1

We study the polynomial approximation of symmetric multivariate functions and of multi-set functions. Specifically, we consider $f (x_{1}, \dots, x_{N})$ , where $x_{i} \in R^{d}$ ,…

Rigorous body-order approximations of an electronic structure potential energy landscape

Jack Thomas, Huajie Chen, Christoph Ortner

We show that the local density of states (LDOS) of a wide class of tight-binding models has a weak body-order expansion. Specifically, we prove that the resulting body-order expans…
