Chebyshev Approximation of Discrete polynomials and Splines
… an integer processor. In many applications, Chebyshev approximation with polynomials and splines is useful in representing a stream of data or a function. Because the impulse/summation approach is developed for discrete systems, some aspects of traditional continuous approximation are not …

Pulse Design for Two-Qubit Gates in Superconducting Circuits
… design problem. Our research indicates that the Chebyshev trajectories – the trajectories based on the Chebyshev pulse and weighted Chebyshev approximation – have the potential to outperform the Slepian trajectories based on the Slepian pulse, which are currently widely used in quantum …

Existence and uniqueness of best approximants, with numerical applications
… which comprises both discrete and continuous Chebyshev approximation. Part II of the thesis contains numerical applications to the approximation of functions, data analysis, mathematical modelling, and optimization. Chapter 7 deals with a modified exchange algorithm for Chebyshev …

Regularized weighted Chebyshev approximations for support estimation
… analysis relies on introducing a new weighted Chebyshev polynomial approximation method, jointly optimizing the bias and variance components of the risk, and combining the weighted minmax polynomial approximation method with discretized semi-infinite programming solvers. Such a setting allows …

Fast algorithms for Brownian dynamics simulation with hydrodynamic interactions
… which are all based on the Krylov subspace approximations, that is, replacing [square root]Dv by p(D)v with p(D) a low degree polynomial in D. We first show rigorously that the popular Chebyshev spectral approximation method (see, for example, [5, 6]) requires [square root][kappa] log …
