In some cases, (1) holds for no value of p: One can show that for each fang there is a unique exponent p 0 such that limn!1 an+1 aq n = 0; q < p C; q = p 1; q > p (the limit superior values of C = 0 or C = 1 at the jump are not ruled out). The objectives set out in the communication are the opening up of the market in order to create new economic opportunities and new possibilities for investment, and the launching of a process of convergence in the area of regulation, making it possible to apply uniform conditions for fair and equitable competition. As with the area of convergence, the area of origin is easily calculated by using BPA software.

If the power series converges on some interval, then the distance from the centre of convergence to the other end of the interval is called the radius of convergence. The method generates a probabilistic map for the area of convergence, directly linking the angles of impact, and their uncertainties, to the projection on the ground of the point of origin. Above the tropopause, due to changes in height of the tropopause caused by the replacement and displacement of mass, warm and cold pockets are found at 200mb and 300mb levels above areas of strong divergence and convergence. This distance is indicated by a dashed line in the example below. By drawing straight lines down the long axis of the blood spatter and noting where the lines intersect, this will indicate the lines of convergence.
