More on doubled Hilbert space in double-scaled SYK
Physics Letters BWe continue our study of the doubled Hilbert space formalism of double-scaled SYK model initiated in Okuyama (2024) [7]. We show that the 1-particle Hilbert space introduced by Lin and Stanford (2023) [6] is related to the doubled Hilbert space H0⊗H0 of ...

Crossing complexity of space-filling curves reveals entanglement of S-phase DNA.
PLoS ONE, 2020 Space-filling curves have been used for decades to study the folding principles of globular proteins, compact polymers, and chromatin. Formally, space-filling curves trace a single circuit through a set of points (x,y,z); informally, they correspond to a

Characterization, Dilation, and Perturbation of Basic Continuous Frames
Journal of Mathematics, 2022 A vector-valued function is called a basic continuous frame if it is a continuous frame for its spanning space. It is shown in this article that basic continuous frames and their oblique duals can be characterized by operators with closed ranges ...

Aproximate Cycles of the Second Kind in Hilbert space for a Generalized Barbashin-Ezeilo Problem
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012 In this work we show that the Volterra integral operator defined on the space of absolutely stable functions induces an asymptotically pseudocontractive operator.

Dynamics for holographic codes
Journal of High Energy Physics, 2020 We describe how to introduce dynamics for the holographic states and codes introduced by Pastawski, Yoshida, Harlow and Preskill. This task requires the definition of a continuous limit of the kinematical Hilbert space which we argue may be achieved via ...

Dilations for Systems of Imprimitivity acting on Banach Spaces
, 2014 Motivated by a general dilation theory for operator-valued measures, framings and bounded linear maps on operator algebras, we consider the dilation theory of the above objects with special structures.

A characterization of Hilbert space [PDF]
Proceedings of the American Mathematical Society, 1974 A real Banach space E of dimension _3 is an inner product space iff there exists a bounded smooth convex subset of E which is the range of a nonexpansive retraction. De Figueiredo and Karlovitz [3] have shown that if E is a strictly convex real finite-dimensional Banach space and dim E> 3 then there can exist no bounded smooth nonexpansive retract of E

Notes on the factorisation of the Hilbert space for two-sided black holes in higher dimensions
Journal of High Energy PhysicsIn this paper, we investigate the Hilbert space factorisation problem of two-sided black holes in high dimensions. We demonstrate that the Hilbert space of two-sided black holes can be factorized into the tensor product of two one-sided bulk Hilbert ...
