A Hankel matrix acting on spaces of analytic functions.
Girela-Álvarez, Daniel
; Merchán-Álvarez, Noel (Springer, 2017-11-02)
If μ is a positive Borel measure on the interval [0, 1) we let H_μ be the Hankel matrix { μ_{n,k} }_{n,k} with entries μ_{n,k} =μ_{n+k}, where, for μ_n denotes the moment of order n of μ. This matrix induces formally an ... -
Best rank k approximation for binary forms.
Ottaviani, Giorgio; Tocino-Sánchez, Alicia (Springer Nature, 2017-09-11)
In the tensor space SymdR2 of binary forms we study the best rank k approximation problem. The critical points of the best rank 1 approximation problem are the eigenvectors and it is known that they span a hyperplane. ... -
Hankel matrices acting on the Hardy space H1 and on Dirichlet spaces.
Girela-Álvarez, Daniel; Merchán-Álvarez, Noel (Springer, 2018-12-03)
If μ is a positive Borel measure on the interval [0, 1) we let H_μ be the Hankel matrix H_μ={ μ_{n,k} }_{n,k} with entries μ_{n,k} =μ_{n+k} where μ_n denotes the moment of order n of μ. This matrix induces formally an ...
