Ring extensions invariant under group action [PDF]
, 2014 Let $G$ be a subgroup of the automorphism group of a commutative ring with identity $T$. Let $R$ be a subring of $T$ such that $R$ is invariant under the action by $G$.

On symmetric units in group algebras
, 2000 Let $U(KG)$ be the group of units of the group ring $KG$ of the group $G$ over a commutative ring $K$. The anti-automorphism $g\mapsto g\m1$ of $G$ can be extended linearly to an anti-automorphism $a\mapsto a^*$ of $KG$. Let $S_*(KG)=\{x\in U(KG) \mid x^*

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background B‐cell lymphoblastic lymphoma (B‐LBL) represents a rare variety of non‐Hodgkin lymphoma, with limited research on its biology, progression, and management. Methods A retrospective analysis was performed on the clinical characteristics of 256 patients aged ≤18 years who received treatment under the China Net Childhood Lymphoma (CNCL)‐

Vanishing of l^2-cohomology as a computational problem
, 2014 We show that it is impossible to algorithmically decide if the l^2-cohomology of the universal cover of a finite CW complex is trivial, even if we only consider complexes whose fundamental group is equal to the elementary amenable group (Z_2 \wr Z)^3.

Isomorphisms of Integral Group Rings of Infinite Groups
Journal of Algebra, 2000 The authors study the isomorphism problem for integral groups rings of infinite groups in particular in connection with the normalizer property. Let \(G\) be a group. \(G\) has the normalizer property for a coefficient domain \(R\) if an automorphism of \(G\) is inner in \(RG\) only when it is inner in \(G\) already.

Integral group ring of the Mathieu simple groupM 12 [PDF]
Rendiconti del Circolo Matematico di Palermo, 2007 We consider the Zassenhaus conjecture for the normalized unit group of the integral group ring of the Mathieu sporadic group M12. As a consequence, we confirm for this group the Kimmerle's conjecture on prime graphs.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Bone tumours present significant challenges for affected patients, as multimodal therapy often leads to prolonged physical limitations. This is particularly critical during childhood and adolescence, as it can negatively impact physiological development and psychosocial resilience.

Deformation theory for prismatic G-displays
Forum of Mathematics, SigmaFor a smooth affine group scheme G over the ring of p-adic integers and a cocharacter $\mu $ of G, we develop the deformation theory for G- $\mu $ -displays over the prismatic site of Bhatt–Scholze, and discuss how our deformation theory can ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The structure of lexical semantic field “jewellery” in the English language
Записки з романо-германської філології, 2015 The article is dedicated to the investigation of the structure of the lexical semantic field “jewellery” in the English language. The semantic relations between jewellery nominations and core-peripheral structure of the given field are analyzed in the ...
