    Exponential convergence of spectral approximations and time-domain computation of scattering problems. by Zhao, Xiaodan.

    Published 2013
    “…The spectral method employs global orthogonal polynomials or Fourier complex exponentials as basis functions, so it enjoys high-order accuracy (with only a few basis functions), if the underlying function is smooth (and periodic in the Fourier case). The typical algebraic order of convergence (i.e., $O(n^{-r})$, where $n$ is the number of polynomial basis functions, and $r$ is related to the Sobolev-regularity of the underlying function), is well documented in various monographs on spectral methods. …”

    Russo–Seymour–Welsh estimates for the Kostlan ensemble of random polynomials by Belyaev, D, Muirhead, S, Wigman, I

    Published 2021
    “…In this paper we establish RSW-type estimates for the nodal sets of the Kostlan ensemble in dimension two, providing a rigorous relation between random algebraic curves and percolation. The estimates are uniform with respect to the degree of the polynomials, and are valid on all relevant scales; this, in particular, resolves an open question raised recently by Beffara–Gayet. …”
