Entropy, 2020 In the differential approach elaborated, we study the evolution of the parameters of Gaussian, mixed, continuous variable density matrices, whose dynamics are given by Hermitian Hamiltonians expressed as quadratic forms of the position and momentum ...

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.

A new perspective on the spatio-temporal variability of soil moisture: temporal dynamics versus time-invariant contributions [PDF]
Hydrology and Earth System Sciences, 2012 Knowledge about the spatio-temporal variability of soil moisture is essential to understand and predict processes in climate science and hydrology. A significant body of literature exists on the characterization of the spatial variability and the rank ...

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

Invariant information and quantum state estimation [PDF]
, 2001 The invariant information introduced by Brukner and Zeilinger, Phys. Rev. Lett. 83, 3354 (1999), is reconsidered from the point of view of quantum state estimation. We show that it is directly related to the mean error of the standard reconstruction from

Infinite Matrices and Invariant Means [PDF]
Proceedings of the American Mathematical Society, 1972 Let a be a one-to-one mapping of the set of positive integers into itself such that av(n)On for all positive integers n and p, where aP(n) = a(a-1(n)), p = 1, 2, . A continuous linear functional p on the space of real bounded sequences is an invariant mean if p(x)_O when the sequence x={x,} has xn_O for all n, p({l, 1, 1, * })=+1, and T({x,(n)})=P(x ...

Thickness in topological transformation semigroups
International Journal of Mathematics and Mathematical Sciences, 1993 This article deals with thickness in topological transformation semigroups (τ-semigroups). Thickness is used to establish conditions guaranteeing an invariant mean on a function space defined on a τ-semigroup if there exists an invariant mean on its ...

Mean action and the Calabi invariant
, 2016 Given an area-preserving diffeomorphism of the closed unit disk which is a rotation near the boundary, one can naturally define an "action" function on the disk which agrees with the rotation number on the boundary.

Some Spaces of Double Sequences Obtained through Invariant Mean and Related Concepts
Abstract and Applied Analysis, 2013 We introduce some double sequences spaces involving the notions of invariant mean (or -mean) and -convergence for double sequences while the idea of -convergence for double sequences was introduced by Çakan et al.
