Relationship between the Riemann and Lebesgue Integrals

The goal of this article is to clarify the relationship between Riemann and Lebesgue integrals. In previous article [5], we constructed a onedimensional Lebesgue measure. The one-dimensional Lebesgue measure provides a measure of any intervals, which can be used to prove the well-known relationship [6] between the Riemann and Lebesgue integrals [1]. We also proved the relationship between the integral of a given measure and that of its complete measure. As the result of this work, the Lebesgue integral of a bounded real valued function in the Mizar system [2], [3] can be calculated by the Riemann integral.National Institute of Technology, Gifu College, 2236-2 Kamimakuwa, Motosu, Gifu, JapanTom M.

A Brief Consideration of The Different Methods of Integration

Any student of mathematics is familiar with the importance of the process of integration. Integration is as fundamental to analysis as the basic principles of the number theory are to arithmetical calculation. Some of the common applications of integration are, finding the distance a falling body has travelled during a particular interval of time; to determine the equation of a curve, given different conditions (such as slope of the curve equal numerically to one-half the abscissa, or some similar problem); motion of a projectile; motion in a resisting medium; finding areas and volumes of revolution; length of a curve; areas of surfaces of revolution; work of expanding gases; and numerous other practical uses. With these many useful applications in mind, the author chose the problem of studying the various methods of integration. It is his earnest desire to learn more about the theory of this interesting subject and to summarize briefly the more familiar definitions of the Riemann and Lebesgue integrals and then to consider less familiar modifications of these definitions. Because of the wealth of material on these subjects, it will be necessary to reduce the discussion of each integral to a minimum. Several important existence theorems will be proven for the Riemann and Lebesgue integrals; followed by a comparison of these two definitions. In discussing the modifications of the above definitions, the author will show the difference between the modification and previous definitions . Lastly, he will offer the opinions of several outstanding mathematicians of the present time regarding the possible trend of integration in the future. In examining the abstracts of theses available in this library and that of the University of Kansas, the author found only one thesis previously written on integration, and that was a Doctor\u27s thesis written on the “Stieltjes integral.

Riemann Versus Lebesgue Integrals

The purpose of this project is to examine how integrals work and compare Reimann integrals to Lebesgue integrals, determining their applications and distinctions
