Bounded extremal problems in Hardy spaces for the conjugate Beltrami equation in simply-connected domains
TL;DR: In this paper, a constrained approximation technique is used to recover solutions to elliptic partial differential equations from incomplete and corrupted boundary data, which involves the use of generalized Hardy spaces of functions whose real and imaginary parts are related by formulae similar to the Cauchy-Riemann equations.
Book ChapterDOI
Some extremal problems linked with indentification from partial frequency data
TL;DR: In this article, a robust identification problem for a linear dynamical control system with incomplete frequency data is considered. But the problem is not solved in the case p = 2. And it is not shown in this paper that the problem can be solved in polynomial time.
Book ChapterDOI
Weighted $H^2$ Approximation of Transfer Functions
Juliette Leblond,Martine Olivi +1 more
TL;DR: In this article, the authors generalize to the case of weighted L 2 spaces some results about L 2 approximation by analytic and rational functions which are useful to perform the identification of unknown transfer functions of stable (linear causal time-invariant) systems from incomplete frequency data.
Journal ArticleDOI
Bounded Extremal and Cauchy–Laplace Problems on the Sphere and Shell
TL;DR: In this paper, a theory of approximating general vector fields on subsets of the sphere in ℝn by harmonic gradients from the Hardy space Hp of the ball, 1
Book ChapterDOI
Approximation problems in some holomorphic spaces, with applications
TL;DR: In this paper, a selection of extremal problems to do with constrained approximation in certain Banach spaces of holomorphic functions, including the classical Hardy spaces and Paley-Wiener spaces, are reviewed.
