Krylov complexity in a natural basis for the Schrödinger algebra
SciPost Physics CoreWe investigate operator growth in quantum systems with two-dimensional Schrödinger group symmetry by studying the Krylov complexity. While feasible for semisimple Lie algebras, cases such as the Schrödinger algebra which is characterized by a semi-direct

Some Operators Associated to Rarita-Schwinger Type Operators [PDF]
arXiv, 2011 In this paper we study some operators associated to the Rarita-Schwinger operators. They arise from the difference between the Dirac operator and the Rarita-Schwinger operators. These operators are called remaining operators. They are based on the Dirac operator and projection operators $I-P_k.$ The fundamental solutions of these operators are harmonic

Robodebt cultures and useful idiots: Why Robodebt was not a techno‐failure
Australian Journal of Social Issues, EarlyView.Abstract Australia's Robodebt scheme is now internationally infamous for how not to use automation in government. Belying heightened concern with artificial intelligence, Robodebt involved traditional, relatively simple computer algorithms to automate the identification and pursuit of alleged historical welfare debts. Yet, it was based on a false legal

On the boundedness of operators in LP(ιq) and Triebel-Lizorkin Spaces
Journal of Function Spaces and Applications, 2008 Given a bounded linear operator T:LPO(ℝn)→Lp1(ℝn), we state conditions under which T defines a bounded operator between corresponding pairs of Lp(ℝn;ιq) spaces and Triebel-Lizorkin spaces Fp,qs(ℝn).

Hardy type unique continuation properties for abstract Schrödinger equations and applications
Electronic Journal of Qualitative Theory of Differential Equations, 2019 In this paper, Hardy's uncertainty principle and unique continuation properties of Schrödinger equations with operator potentials in Hilbert space-valued $L^{2}$ classes are obtained.

Positivity, Betweenness and Strictness of Operator Means [PDF]
arXiv, 2014 An operator mean is a binary operation assigned to each pair of positive operators satisfying monotonicity, continuity from above, the transformer inequality and the fixed-point property. It is well known that there are one-to-one correspondences between operator means, operator monotone functions and Borel measures.

Local operator system structures and their tensor products [PDF]
arXiv, 2020 We introduce and explore the theory of tensor products in the category of local operator systems. Analogous to minimal operator system OMIN and maximal operator system OMAX, minimal and maximal local operator system structures LOMIN and LOMAX, respectively, are also discussed.
arxiv
, 1999 Let {Tt}t>0 be the semigroup of linear operators generated by a Schrodinger operator -A = ? - V, where V is a nonnegative potential that belongs to a certain reverse Holder class. We define a Hardy space HA1 by means of a maximal function associated with

Localized and Extended Phases in Square Moiré Patterns
Annalen der Physik, EarlyView.Rotated superimposed lattices in two dimensions, the termed moiré patterns, represent a clear example of how the structure affects the physical properties of a particle moving on it. A robust numerical treatment of continuous and discrete models leads to confirm that while localized states result from angles that produce non‐commensurable lattices ...
