Journal of Lie Theory, 2016 A representation $π$ of a locally compact group $G$ is called \e{trace class}, if for every test function $f$ the induced operator $π(f)$ is a trace class operator. The group $G$ is called \e{trace class}, if every $π\in G$ is trace class. We show that trace class groups are type I and give a criterion for semi-direct products to be trace class and ...

Mathematische Nachrichten, 2023 AbstractPro‐ groups of finite powerful class are studied. We prove that these are ‐adic analytic, and further describe their structure when their powerful class is small. It is also shown that there are only finitely many finite ‐groups of fixed coclass and powerful class.

Isomorphism versus commensurability for a class of finitely presented groups
, 2014 We construct a class of finitely presented groups where the isomorphism problem is solvable but the commensurability problem is unsolvable. Conversely, we construct a class of finitely presented groups within which the commensurability problem is ...

Minimal Polynomials of Some Eta-Quotients Evaluated at CM Points
MathematicsWe study certain eta-quotients of weight zero evaluated at CM points of imaginary quadratic orders. Using the theory of extended form class groups, we show that these special values generate the corresponding ring class fields and we provide explicit ...

Class Groups and Selmer Groups
Journal of Number Theory, 1996 It is often the case that a Selmer group of an abelian variety and a group related to an ideal class group can both be naturally embedded into the same cohomology group. One hopes to compute one from the other by finding how close each is to their intersection.

manuscripta mathematica, 1991 Using elementary lattice theoretic and linear algebraic techniques, the authors classify up to isomorphism and up to quasi-isomorphism the strongly indecomposable Butler groups that occur as quotients of a finite rank completely decomposable torsion-free abelian group modulo a rank 1 pure subgroup.

$N$-recognizability of Groups $ Alt_p\times Alt_5$,\\ Where $p>1361$ Is a Prime Number
Известия Иркутского государственного университета: Серия "Математика"$N$-recognizability of Groups $ Alt_p\times Alt_5$, Where $p>1361$ Is a Prime Number} Given a finite group $L$, let $N(L)$ denote the set of its conjugacy class sizes.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
