COUNTING CONJUGACY CLASSES IN [PDF]
, 2018 We show that if a finitely generated group$G$has a nonelementary WPD action on a hyperbolic metric space$X$, then the number of$G$-conjugacy classes of$X$-loxodromic elements of$G$coming from a ball of radius$R$in the Cayley graph of$G$grows ...

On functional moduli of surface flows
Pracì Mìžnarodnogo Geometričnogo Centru, 2020 Currently, an complete topological classification has been obtained with respect to the topological equivalence of Morse-Smale flows, [9, 7], as well as their generalizations of Ω-stable flows on closed surfaces, [4].

Conjugacy Class Representatives in the Monster Group [PDF]
LMS Journal of Computation and Mathematics, 2005 AbstractThe paper describes a procedure for determining (up to algebraic conjugacy) the conjugacy class in which any element of the Monster lies, using computer constructions of representations of the Monster in characteristics 2 and 7. This procedure has been used to calculate explicit representatives for each conjugacy class.

Normality of closure of nilpotent conjugacy classes [PDF]
, 2022 In this work the author studies the geometry of the conjugacy classes in the space of matrices and in its subspaces of symmetric and skew-symmetric matrices under the actions of the general linear group, the orthogonal group and the symplectic group.

The undirected power graph on the conjugacy classes of a finite group [PDF]
AUT Journal of Mathematics and ComputingLet $G$ be a finite group. The undirected power graph on the conjugacy classes of $G$ is the simple graph $\mathcal{P_C}(G)$ whose vertices are the conjugacy classes of $G$ and two distinct vertices $C$ and $C'$ are adjacent if one is a subset of a power

Two-Transitive Actions on Conjugacy Classes [PDF]
, 1999 Every group acts transitively by conjugation on each of its conjugacy classes of elements. It is natural to wonder when this action becomes multiply transitive.

Line Graphs of Multigraphs and the Forbidden Graph E 6
Journal of Graph Theory, EarlyView.ABSTRACT The line graph Γ of a multigraph Δ is the graph whose vertices are the edges of Δ, where two such edges are adjacent if and only if they meet in a single vertex of Δ. We provide several characterizations of such line graphs and in particular show that a graph is a line graph if and only if it does not contain one of the 32 graphs, all of which

Bayesian Inference for Multivariate Monotone Densities
Scandinavian Journal of Statistics, EarlyView.ABSTRACT We consider a nonparametric Bayesian approach to estimation and testing for a multivariate monotone density. Instead of following the conventional Bayesian approach of imposing a prior that satisfies the monotonicity restriction, we place a prior on the step heights via binning and a Dirichlet distribution. The resulting posterior distribution

Topological conjugacy of non-singular flows with two limit cycles on $S^2 times S^1$
Журнал Средневолжского математического общества, 2022 In the paper, non-singular flows with two limit cycles on the manifold $S^2 times S^1$ are considered. For such flows, a classification is obtained up to topological conjugacy, and it is shown that they have a functional modulus of stability.

Scandinavian Journal of Statistics, EarlyView.ABSTRACT A possibly time‐dependent transition intensity matrix or generator (Q(t))$$ \left(Q(t)\right) $$ characterizes the law of a Markov jump process (MP). For a time‐homogeneous MP, the transition probability matrix (TPM) can be expressed as a matrix exponential of Q$$ Q $$.
