We consider a family of skew tent maps fa on the unit interval, determined by parameter a, with 0<a<1. give decision procedure, that input and point x0 in determines whether or not sequence x0,fa(x0),fa2(x0),... iterates reaches one two fixed points after finite number iterations.

IT capabilities, including IT governance, are widely believed to affect the value organizations derive from IT. This paper focuses on what may be an important strategy for building enterprise-wide IT capabilities in large decentralized organizations: undertaking an IT centralizing reorganization to concentrate authority for IT activities and decisions at the headquarters level of an enterprise....

Fix the data (p,K,E) where p is a prime number, K a number field, and E an elliptic curve over Q. Let K∞/K denote the maximal Zp-power extension of K. Recent work provides, in some instances, detailed information about p-adic completions of Mordell-Weil groups and their associated p-adic height pairings, and the p-primary Shafarevich-Tate groups and their associated Cassels pairings, over inter...

Neural maps are a very popular class of unsupervised neural networks that project high-dimensional data of the input space onto a neuron position in a low-dimensional output space grid. It is desirable that the projection effectively preserves the structure of the data. In this paper we present a hybrid model called K-Dynamical Self Organizing Maps (KDSOM ) consisting of K Self Organizing Maps ...

Two digraphs of same order are said to be skew-equienergetic if their skew energies are equal. One of the open problems proposed by Li and Lian was to construct non-cospectral skew-equienergetic digraphs on n vertices. Recently this problem was solved by Ramane et al. In this  paper, we give some new methods to construct new skew-equienergetic digraphs.

For any C-algebra A let A denote the set of all positive elements in A. A state on a unital C-algebra A is a linear functional ω : A → C such that ω(a) ≥ 0 for every a ∈ A and ω(I) = 1 where I is the unit of A. By S(A) we will denote the set of all states on A. For any Hilbert space H we denote by B(H) the set of all bounded linear operators on H . A linear map φ : A → B between C-algebras is c...

&nbsp;In this paper, we consider a flexible skew-generalized normal distribution. This distribution is denoted by $FSGN(/lambda _1, /lambda _2 /theta)$. It contains the normal, skew-normal (Azzalini, 1985), skew generalized normal (Arellano-Valle et al., 2004) and skew flexible-normal (Gomez et al., 2011) distributions as special cases. Some important properties of this distribution are establi...
