Hilbert matrix norm

In linear algebra, a Hilbert matrix, introduced by Hilbert (1894), is a square matrix with entries being the unit fractions $${\displaystyle H_{ij}={\frac {1}{i+j-1}}.}$$For example, this is the 5 × 5 Hilbert matrix: See more Hilbert (1894) introduced the Hilbert matrix to study the following question in approximation theory: "Assume that I = [a, b], is a real interval. Is it then possible to find a non-zero polynomial P with integer coefficients, such … See more The method of moments applied to polynomial distributions results in a Hankel matrix, which in the special case of approximating a … See more The Hilbert matrix is symmetric and positive definite. The Hilbert matrix is also totally positive (meaning that the determinant of every submatrix is positive). The Hilbert matrix is an example of a Hankel matrix. It is also a specific example of a See more • Hilbert, David (1894), "Ein Beitrag zur Theorie des Legendre'schen Polynoms", Acta Mathematica, 18: 155–159, doi:10.1007/BF02418278 See more WebSep 14, 2024 · The Hilbert matrix \({\mathrm {H}}\) and its action on the space \(\ell ^2\) consisting of square summable sequences was first studied in [], where Magnus described the spectrum of the Hilbert matrix.Thereafter Diamantopoulos and Siskakis in [3, 4] begin to study the action of the Hilbert matrix on Hardy and Bergman spaces, which can be seen …

WebIn mathematics, Hilbert spaces (named after David Hilbert) allow generalizing the methods of linear algebra and calculus from (finite-dimensional) Euclidean vector spaces to spaces that may be infinite-dimensional.Hilbert spaces arise naturally and frequently in mathematics and physics, typically as function spaces.Formally, a Hilbert space is a … WebOct 18, 2024 · We find the lower bound for the norm of the Hilbert matrix operator H on the weighted Bergman space Ap,α We show that if 4 ≤ 2 (α + 2) ≤ p, then ∥ H ∥ Ap,α → Ap,α = , while if 2 ≤ α +2 < p < 2 (α+2), upper bound for the norm ∥ H ∥ Ap,α → Ap,α, better then known, is obtained. MSC classification These norms treat an matrix as a vector of size , and use one of the familiar vector norms. For example, using the p-norm for vectors, p ≥ 1, we get: This is a different norm from the induced p-norm (see above) and the Schatten p-norm (see below), but the notation is the same. The special case p = 2 is the Frobenius norm, and p = ∞ yields the maximum norm. t stockchase

The Frobenius norm can also be considered as a vector norm .

WebMatrix Norms: It is often desirable to have a notion of the \size" of a matrix, like the norm or magnitude of a vector. One way to manufacture such a thing is simply to regard the n2 entries of a matrix A2M n(R) as the components of a vector in Rn 2 and take its Euclidean norm. The resulting quantity is usually called the Hilbert-Schmidt norm ...
