abstract in this paper we test two versions of convergence hypothesis namely deterministic or conditional convergence and stochastic or catching up hypothesis using carrion-i-silvestre et al. (2005) stationary test. the results show latin and south american countries (lsa) catching up process toward the usa failed in 1980s and somewhat in 1990s. but in 2000s most of them could lie in convergenc...

In this paper, we study some basic properties of bicomplex numbers. We introduce two different types partial order relations on numbers, discuss valued metric spaces with respect to orders, and compare them. also define a hyperbolic space, the density natural statistical convergence, Cauchy property sequence numbers investigate in space prove that is complete if only complex are complete.

This study is about neutrosophic structures, which one of the popular topics recent days. In this study, different types convergence concepts were applied to difference sequences. With help properties double type sequences, concept sequences combined with structures that are advantageous work like Lacunary

We introduce some notions of variation using the statistical convergence with respect to power series method. By use variation, we prove criterions that can be used verify without limit value. Also, results give relations between P-statistical variations are studied.
