Fixed point properties for semigroups of nonexpansive mappings on convex sets in dual Banach spaces
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018 It has been a long-standing problem posed by the first author in a conference in Marseille in 1990 to characterize semitopological semigroups which have common fixed point property when acting on a nonempty weak* compact convex subset of a dual Banach ...

A Bi-Invariant Statistical Model Parametrized by Mean and Covariance on Rigid Motions
Entropy, 2020 This paper aims to describe a statistical model of wrapped densities for bi-invariant statistics on the group of rigid motions of a Euclidean space. Probability distributions on the group are constructed from distributions on tangent spaces and pushed to

An amenability-like property of finite energy path and loop groups
Comptes Rendus. Mathématique, 2021 We show that the groups of finite energy loops and paths (that is, those of Sobolev class $H^1$) with values in a compact connected Lie group, as well as their central extensions, satisfy an amenability-like property: they admit a left-invariant mean on ...

On the inversion invariance of invariant means [PDF]
Proceedings of the American Mathematical Society, 1965 An invariant mean on a group G is a normalized, positive, translation invariant linear functional defined on the space of cll bounded complex valued functions on G. Some groups possess an invariant mean (or are said to be amenable), while others do not. In particular, all abelian groups are amenable [2, ?17.5 ]. An invariant mean on a group need not be

Mean-of-Order-p Location-Invariant Extreme Value Index Estimation
Revstat Statistical Journal, 2016 A simple generalisation of the classical Hill estimator of a positive extreme value index (EVI) has been recently introduced in the literature. Indeed, the Hill estimator can be regarded as the logarithm of the mean of order p = 0 of a certain set of ...

Invariant foreground occupation ratio for scale adaptive mean shift tracking
IET Computer Vision, 2015 The mean shift algorithm has been introduced successfully into the field of computer vision to be an efficient approach for visual tracking but the tracker has been awkward in handling the scale change of the object.

Chen optimal inequalities of CR-warped products of generalized Sasakian space form
Journal of Taibah University for Science, 2020 Our main objective of this paper is to derive the relationship between the main extrinsic invariant, and the contact CR δ-invariant (new intrinsic invariant) on a generic submanifold in trans-Sasakian generalized Sasakian space forms.

Conjugation-invariant means [PDF]
Colloquium Mathematicum, 1987 Let \(G\) be a locally compact group, \(dx\) a left invariant measure, \((\tau_ x' f)(y)=f(xyx^{-1})\), \(x\in G\), \(f\in L^{\infty}(G)\) and \(\tau_ x\) the adjoint of \(\tau_ x'\) on \(L'(G)\). A nonnegative linear function M on \(L^{\infty}(G)\) is called a mean if \(M(1)=1\); a mean \(M\) is conjugate invariant if \(M(\tau_ x' f)=M(f)\) for all ...

On the invariant mean and statistical convergence
Applied Mathematics Letters, 2009 The authors introduce two kinds of summability methods, \(\sigma\)-statistical summability and statistical \(\sigma\)-summability, by using the concepts of invariant means, and statistical convergence. A sequence \((x_{k})\) is said to be \(\sigma\)-statistically convergent to \(L\) if for every \( \varepsilon> 0\) \[ \lim_{p\rightarrow\infty}\frac{1 ...

Totally umbilical proper slant submanifolds of para-Kenmotsu manifold
Cubo, 2019 In this paper, we study slant submanifolds of a para-Kenmotsu manifold. We prove that totally umbilical slant submanifold of a para-Kenmotsu manifold is either invariant or anti-invariant or dimension of submanifold is 1 or the mean curvature vector H of
