A strict mathematical definition of integrals by Bornhard · Riemann gives (see the entry "Riemann integrals"). Riemann's definition uses the concept of limit, imagining the curved trapezium as the limit of a series of rectangular combinations. Starting from the 19th century, more advanced definitions of integrals gradually emerged, including integrals for various types of functions over various integral fields. For example, path integral is the integral of a multivariate function. The interval of the integral is no longer a line segment (interval [a, b]), but a curve segment on a plane or in space; in area integral, the curve is divided into three-dimensional space replaced by a surface. The integration of differential forms is a fundamental concept in differential geometry.
