A complex fuzzy set (CFS) is described by a complex-valued truth membership function, which combination of standard true function plus phase term. In this paper, we extend the idea graph (FG) to (CFG). The CFS complexity arises from variety values that its can attain. contrast range expanded plane’s unit circle rather than [0,1]. As result, provides mathematical structure for representing in te...

in this paper we introduce two symmetric variants of amenability, symmetric module amenability and symmetric connes amenability. we determine symmetric module amenability and symmetric connes amenability of some concrete banach algebras. indeed, it is shown that $ell^1(s)$ is  a symmetric $ell^1(e)$-module amenable if and only if $s$ is amenable, where $s$ is an inverse semigroup with subsemigr...

In this paper we have considered two one parametric generalizations. These two generalizations have in particular the well known measures such as: J-divergence, Jensen-Shannon divergence and arithmetic-geometric mean divergence. These three measures are with logarithmic expressions. Also, we have particular cases the measures such as: Hellinger discrimination, symmetric χ2−divergence, and trian...

A finite difference method is developed for solving symmetric positive differential equations in the sense of Friedrichs. The method is applicable to partial differential equations of mixed type with more general boundary conditions. The method is shown to have a convergence rate of 0(hxl2), h being the size of mesh grid. Some numerical results are presented for a model problem of forward-backw...

Abstract. We study difference sets with parameters (v, k, λ) = (ps(r2m − 1)/(r − 1), ps−1r2m−1, ps−2(r − 1)r2m−2), where r = (ps − 1)/(p − 1) and p is a prime. Examples for such difference sets are known from a construction of McFarland which works for m = 1 and all p, s. We will prove a structural theorem on difference sets with the above parameters; it will include the result, that under the ...

Abstract— One of the important applications of Radar is to track and search the target in interfering environment. Which requires design of an array antenna with the most important property is, the ability to form precisely located deep pattern null for angle tracking. In this paper an attempt is made to analyze difference patterns for some of the odd symmetric excitation amplitude functions. T...
