Classification of periodic transformations of an orientable surface of genus two
Журнал Средневолжского математического общества, 2021 In this paper, we find all admissible topological conjugacy classes of periodic transformations of a two-dimensional surface of genus two. It is proved that there are exactly seventeen pairwise topologically non-conjugate orientation-preserving periodic ...

Closures of conjugacy classes in g2
Journal of Algebra, 1989 Let \(\mathfrak g\) be the simple Lie algebra of type \(G_2\) and \(C_i\) be the nilpotent conjugacy class in \(\mathfrak g\) of dimension \(i = 6, 8, 10\) and \(12\). In this paper the author shows the following: (a) every conjugacy class of \(\mathfrak g\) except \(C_8\) has a normal closure with rational singularities, (b) [\textit{T. Levasseur} and

On intersections of conjugacy classes and bruhat cells [PDF]
Transformation Groups, 2010 For a connected complex semi-simple Lie group $G$ and a fixed pair $(B, B^-)$ of opposite Borel subgroups of $G$, we determine when the intersection of a conjugacy class $C$ in $G$ and a double coset $BwB^-$ is non-empty, where $w$ is in the Weyl group $W$ of $G$.

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.ABSTRACT With the development of modern technology, richer and more intensive longitudinal data are available for researchers to study more complex model structures. The Mixed‐Effect Location‐Scale Model (MELS) is useful for modeling the variance components in such data.

Commuting involution graphs for [(A)\tilde]n
, 2006 In this article we consider the commuting graphs of involution conjugacy classes in the affine Weyl group A~n. We show that where the graph is connected the diameter is at most 6.

Groups with iterated restrictions on conjugacy classes
, 2023 Let be a group class (such as the class of all finite groups). Starting from , we can define the class C of all groups G such that, for any g G, the co-centralizer G/CG((g)G) of g in G is an -group; of course, if = , these are the well-known FC-groups ...

Coprime invariable generation and minimal-exponent groups
, 2015 Colva Roney-Dougal acknowledges the support of EPSRC grant EP/I03582X/1.A finite group G is coprimely invariably generated if there exists a set of generators {g1,. .,gu} of G with the property that the orders |g1|,.

Conjugacy Classes of Reflections of Maps
Journal of Mathematical Sciences, 2017 This paper considers how many conjugacy classes of reflections a map can have, under various transitivity conditions. It is shown that for vertex- and for face-transitive maps there is no restriction on their number or size, whereas edge-transitive maps can have at most four classes of reflections.

Bayesian Inference for Joint Estimation Models Using Copulas to Handle Endogenous Regressors
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 3, Page 519-534, June 2026.ABSTRACT This study proposes a Bayesian approach for finite‐sample inference of the Gaussian copula endogeneity correction. Extant studies use frequentist inference, build on a priori computed estimates of marginal distributions of explanatory variables, and use bootstrapping to obtain standard errors. The proposed Bayesian approach facilitates precise

GROUPS WITH SMALL CONJUGACY CLASSES
Tamkang Journal of Mathematics, 1999 A group satisfies property (*) iff every conjugacy class has size not greater than 2. This paper proves properties of this type of group and conclude that it is a central product of an abelian group with 2-groups that are "almost" extra special.
