Linear Groups with Many Profinitely Closed Subgroups [PDF]
Advances in Group Theory and Applications, 2017 If G is a linear group with every subgroup of G of infinite Prüfer rank closed in the profinite topology on G, we prove that either every subgroup of G is closed in this topology or G itself has finite Prüfer rank.

On Projective Modules of Finite Rank [PDF]
Proceedings of the American Mathematical Society, 1969 One of the aims of this paper is to answer the following question: Let R be a commutative ring for which projective ideals are finitely generated; is the same valid in R [x], the polynomial ring in one variable over R? A Hilbert basis type of argument does not seem to lead directly to a solution.

Advanced Engineering Materials, EarlyView.This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

On one class of modules over group rings with finiteness restrictions [PDF]
International Journal of Group Theory, 2014 The author studies the $bf R$$G$-module $A$ such that $bf R$ is an associative ring, a group $G$ has infinite section $p$-rank (or infinite 0-rank), $C_{G}(A)=1$, and for every proper subgroup $H$ of infinite section $p$-rank (or infinite 0-rank ...

Finite rank perturbations of singular spectra [PDF]
Proceedings of the American Mathematical Society, 1986 Let T T be selfadjoint, and V V nonnegative of finite rank, with the range of V V cyclic for T T . Then the singular parts of T T and H = T + V H = T + V are supported on two sets S

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Finite simple groups of low rank: Hurwitz generation and (2,3)-generation [PDF]
International Journal of Group Theory, 2015 Let us consider the set of non-abelian finite simple groups which admit non-trivial irreducible projective representations of degree ≤7 over an algebraically closed field F of characteristic p≥0 .

International Journal of Mathematics and Mathematical Sciences, 1984 In this paper we continue the study of projective planes which admit collineation groups of low rank (Kallaher [1] and Bachmann [2,3]). A rank 5 collineation group of a projective plane ℙ of order n≠3 is proved to be flag-transitive. As in the rank 3 and

Finite Cartan Graphs Attached to Nichols Algebras of Diagonal Type
Advances in Mathematical Physics, 2021 Nichols algebras are fundamental objects in the construction of quantized enveloping algebras and in the classification of pointed Hopf algebras by the lifting method of Andruskiewitsch and Schneider. The structure of Cartan graphs can be attached to any
