Generalized invertibility of hankel and toeplitz matrices
Linear Algebra and its Applications, 1993 A result for the computation of the Moore-Penrose inverse of Hankel matrices over the field of complex numbers has been given by \textit{G. Heinig} and \textit{K. Rost} [Algebraic methods for Toeplitz-like matrices and operators (1984; Zbl 0549.15013)].

Product of Rectangular Toeplitz (Hankel) Matrices
Computational Mathematics and Mathematical PhysicsIn this paper, we study products of asymmetric Toeplitz matrices, we give necessary and sufficient conditions for the product of two asymmetric Toeplitz matrices compatible sizes is asymmetric Toeplitz matrix. We also give some results related to the isometry.

Hankel Matrices Acting on the Dirichlet Space
Journal of Fourier Analysis and ApplicationsThe characterization of the boundedness of operators induced by Hankel matrices on analytic function spaces can be traced back to the work of Z. Nehari and H. Widom on the Hardy space, and has been extensively studied on many other analytic function spaces recently. However, this question remains open in the context of the Dirichlet space [20].

Stable Factorization of Hankel and Hankel-like Matrices
, 1998 This paper gives displacement structure algorithms for the factorization positive definite and indefinite Hankel and Hankel-like matrices. The positive definite algorithm uses orthogonal symplectic transformations in place of the -orthogonal ...

The geometry of the modular bootstrap
Journal of High Energy PhysicsWe explore the geometry behind the modular bootstrap and its image in the space of Taylor coefficients of the torus partition function. In the first part, we identify the geometry as an intersection of planes with the convex hull of moment curves on R ...
