Hierarchy of Topological Order From Finite-Depth Unitaries, Measurement, and Feedforward
PRX Quantum, 2023 Long-range entanglement—the backbone of topologically ordered states—cannot be created in finite time using local unitary circuits, or, equivalently, adiabatic state preparation.

Minimal sumsets in finite solvable groups
Discrete Mathematics, 2010 Given a group \(G\) and positive integers \(r,s\leq |G|\), the authors denote by \(\mu_G(r,s)\) the least possible size of a product set \(AB=\{ab\mid a\in A,\;b\in B\}\), where \(A,B\) run over all subsets of \(G\) of size \(r,s\), respectively. In a previous paper, they have completely determined \(\mu_G\) when \(G\) is Abelian [J. Algebra 287, No. 2,

2-elements in an Autotopism Group of a Semifield Projective Plane
Известия Иркутского государственного университета: Серия "Математика", 2022 We investigate the well-known hypothesis of D.R. Hughes that the full collineation group of non-Desarguesian semifield projective plane of a finite order is solvable (the question 11.76 in Kourovka notebook was written down by N.D. Podufalov). The spread

Solvable Generation of Finite Groups
Hokkaido Mathematical Journal, 1987 Aschbacher and Guralnick have proved that an arbitrary finite group G is generated by a pair of conjugate solvable subgroups. Here the author shows that some conditions can be imposed on how the generating subgroups are embedded in G. Theorem: A finite group G contains a self-normalizing solvable subgroup S such that (i) \(G=\) for some g in G and (ii)

Solvable graphs of finite groups
Hacettepe Journal of Mathematics and Statistics, 2020 Let $G$ be a finite non-solvable group with solvable radical $Sol(G)$. The solvable graph $\Gamma_s(G)$ of $G$ is a graph with vertex set $G\setminus Sol(G)$ and two distinct vertices $u$ and $v$ are adjacent if and only if $\langle u, v \rangle$ is solvable.

Predicting EHL film thickness parameters by machine learning approaches
Friction, 2022 Non-dimensional similarity groups and analytically solvable proximity equations can be used to estimate integral fluid film parameters of elastohydrodynamically lubricated (EHL) contacts.

Arthritis Care &Research, EarlyView.Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

$p$-solvable linear groups of finite order [PDF]
Transactions of the American Mathematical Society, 1971 The purpose of this paper is to prove the following result. Theorem. Let p be an odd prime and let G be a finite p-solvable group. Assume that G has a faithful representation of degree n over a field of characteristic zero or over a perfect field of characteristic p.

Orbits of finite solvable groups on characters [PDF]
Israel Journal of Mathematics, 2013 We prove that if a solvable group A acts coprimely on a solvable group G, then A has a "large" orbit in its corresponding action on the set of ordinary complex irreducible characters of G. This extends (at the cost of a weaker bound) a 2005 result of A. Moreto who obtained such a bound in case that A is a p-group.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
International Journal of Adaptive Control and Signal Processing, EarlyView.Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...
