Summability methods are mathematical techniques used to assign values to certain divergent series or to improve the convergence of convergent series. These methods are crucial in various areas of mathematics, including analysis, number theory, and numerical mathematics. The idea behind summability is to provide a way to assign a meaningful value or limit to series that do not converge in the traditional sense. Several types of summability methods exist, each with its own specific approach and areas of application.

A Constant Altitude Plan Position Indicator (CAPPI) is a type of radar display used in meteorology and aviation. It provides a two-dimensional horizontal view of atmospheric phenomena, such as precipitation, at a constant altitude. This capability allows meteorologists and pilots to analyze weather conditions without the interference of varying altitudes.
