The relationship between economic growth and inflation a concern for many countries in the developed and developing world, and erected in developed countries, a lot of research to laparoscopy relationship in order to overcome the problems that may be exposed to the States as a result of this association. The current research is an attempt to explore the trends in this relationship in Iraq in order to determine the ranges that can affect or be affected by growth as a result of inflation, period $(1990-2020)$ was adopted to range time frame in which you can determine the nature of the relationship between the two variables as well have been taking data at their nominal value as terms of GDP growth for the accurate diagnosis of the impact of inflation has been relying on time-series analysis to prove the direction of the relationship, and the paper confirmed the conclusion that there are two methods of fundamental bond that link inflation and economic growth in Iraq.

Let G be a finite group. For gin G, an ordered pair $(x_1,y_1)in Gtimes G$ is called a solution of the commutator equation $[x,y]=g$ if $[x_1,y_1]=g$. We consider rho_g(G)={(x,y)| x,yin G, [x,y]=g}, then the probability that the commutator equation $[x,y]=g$ has solution in a finite group $G$, written P_g(G), is equal to frac{|rho_{g}(G)|}{|G|^2}. In this paper, we present two methods for the computing P_g(G). First by $GAP, we give certain explicit formulas for P_g(A_n) and P_g(S_n). Also we note that this method can be applied to any group of small order. Then by using the numerical solutions of the equation xy-zu equiv t (mod~n), we derive formulas for calculating the probability of $rho_g(G)$ where $G$ is a two generated group of nilpotency class 2.the formula is not displayed correctly!

In an earlier work we showed that for ordered fields F not isomorphic to the reals R, there are continuous 1-1 functions on [0, 1]F which map some interior point to a boundary point of the image (and so are not open). Here we show that over closed bounded intervals in the rationals Q as well as in all non-Archimedean ordered fields of countable cofinality, there are uniformly continuous 1-1 functions not mapping interior to interior. In particular, the minimal non-Archimedean ordered field Q(x), as well as ordered Laurent series fields with coefficients in an ordered field accommodate such pathological
functions.
