this paper examines the problematization of cultural issues related tothe dual spacization of life. the emergence of the second space of lifeover the first place of life combining local and translocal, national andtransnational capacities and challenges. we discuss the capacities andopportunities occurring through the instant communication industrywhich made the spontaneous connection between a...

For an automorphism ϕ of a free group Fn rank n, Bestvina and Handel showed that the rk(Fix(ϕ)) fixed subgroup is not greater than n. Soon after Handel's announcement, their result was generalized by many authors in various directions. In this paper, we are interested subgroups endomorphisms products, focusing on explicit bounds for ranks. By introducing concept UFP degree combining some result...

In this paper, we prove that every metric line in the Poincare ball model of hyperbolic geometry is exactly a classical line of itself. We also proved nonexistence of periodic lines in the Poincare ball model of hyperbolic geometry.

For solving large sparse non-Hermitian positive definite linear equations, Bai et al. proposed the Hermitian and skew-Hermitian splitting methods (HSS). They recently generalized this technique to the normal and skew-Hermitian splitting methods (NSS). In this paper, we present an accelerated normal and skew-Hermitian splitting methods (ANSS) which involve two parameters for the NSS iteration. W...

In recent years, the skew-normal models introduced in Azzalini (1985) have enjoyed an amazing success, although an important literature has reported that they exhibit, in the vicinity of symmetry, singular Fisher information matrices and stationary points in the profile log-likelihood function for skewness, with the usual unpleasant consequences for inference. For general multivariate skew-symm...

‎‎a natural generalization of two dimensional cyclic code ($t{tdc}$) is two dimensional skew cyclic code‎. ‎it is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $r_n:=f[x,y;rho,theta]/_l$‎. ‎in this paper we characterize the left ideals of the ring $r_n$ with two methods and find the generator matrix for two dimensional s...

Intraday high-frequency data of stock returns exhibit not only typical characteristics (e.g., volatility clustering and the leverage effect) but also a cyclical pattern return that is known as intraday seasonality. In this paper, we extend stochastic (SV) model for application with such develop an efficient Markov chain Monte Carlo (MCMC) sampling algorithm Bayesian inference proposed model. Ou...

This paper shows that a large class of chaotic systems, introduced in Celikovsky and Chen [7], as the hyperbolic-type generalized Lorenz system, can be systematically used to generate synchronized chaotic oscillations. While the generalized Lorenz system unifies the famous Lorenz system and Chen's system [10], the hyperbolic-type generalized Lorenz system is in some way complementary to it. Syn...
