Fast and Efficient Stochastic Optimization for Analytic Continuation
F. Bao, Y. Tang, M. Summers +4
The analytic continuation of imaginary-time quantum Monte Carlo data to extract real-frequency spectra remains a key problem in connecting theory with experiment. Here we present a…
On the Lebesgue Constant of Weighted Leja Points for Lagrange Interpolation on Unbounded Domains
Peter Jantsch, Clayton G. Webster, Guannan Zhang
This work focuses on weighted Lagrange interpolation on an unbounded domain, and analyzes the Lebesgue constant for a sequence of weighted Leja points. The standard Leja points are…
Polynomial approximation via compressed sensing of high-dimensional functions on lower sets
Abdellah Chkifa, Nick Dexter, Hoang Tran +1
This work proposes and analyzes a compressed sensing approach to polynomial approximation of complex-valued functions in high dimensions. Of particular interest is the setting wher…
