A finitely presented infinite simple group of homeomorphisms of the circle [PDF]
Journal of the London Mathematical Society, 2018 We construct a finitely presented, infinite, simple group that acts by homeomorphisms on the circle, but does not admit a non-trivial action by $C^1$-diffeomorphisms on the circle. The group emerges as a group of piecewise projective homeomorphisms of $S^

Simple group fMRI modeling and inference. [PDF]
Neuroimage, 2009 While many advanced mixed-effects models have been proposed and are used in fMRI, the simplest, ordinary least squares (OLS), is still the one that is most widely used. A survey of 90 papers found that 92% of group fMRI analyses used OLS.

Classifying cubic symmetric graphs of order 52p2; pp. 55–60 [PDF]
Proceedings of the Estonian Academy of Sciences, 2023 An automorphism group of a graph is said to be s-regular if it acts regularly on the set of s-arcs in the graph. A graph is s-regular if its full automorphism group is s-regular.

Simple and Fast Group Robustness by Automatic Feature Reweighting [PDF]
International Conference on Machine Learning, 2023 A major challenge to out-of-distribution generalization is reliance on spurious features -- patterns that are predictive of the class label in the training data distribution, but not causally related to the target.

A NEW CHARACTERIZATION OF SIMPLE GROUP G 2 (q) WHERE q ⩽ 11 [PDF]
Journal of Algebraic Systems, 2020 Let G be a finite group , in this paper using the order and largest element order of G we show that every finite group with the same order and largest element order as G 2 (q), where q ⩽ 11 is necessarily isomorphic to the group G 2 (q)

A 2-arc Transitive Hexavalent Nonnormal Cayley Graph on A119
Mathematics, 2021 A Cayley graph Γ=Cay(G,S) is said to be normal if the base group G is normal in AutΓ. The concept of the normality of Cayley graphs was first proposed by M.Y.

Reduced designs constructed by Key-Moori Method $2$ and their connection with Method $3$ [PDF]
AUT Journal of Mathematics and Computing, 2023 For a 1-$(v,k,\lambda)$ design $\mathcal{D}$ containing a point $x$, we study the set $I_x$, the intersection of all blocks of $\mathcal{D}$ containing $x$.

On the uniform domination number of a finite simple group [PDF]
Transactions of the American Mathematical Society, 2017 Let $G$ be a finite simple group. By a theorem of Guralnick and Kantor, $G$ contains a conjugacy class $C$ such that for each non-identity element $x \in G$, there exists $y \in C$ with $G = \langle x,y\rangle$. Building on this deep result, we introduce

The depth of a finite simple group [PDF]
, 2017 We introduce the notion of the depth of a finite group $G$, defined as the minimal length of an unrefinable chain of subgroups from $G$ to the trivial subgroup. In this paper we investigate the depth of (non-abelian) finite simple groups.
