	Integral - Wikipedia, the free encyclopedia
		Intuitively, the integral of a continuous, positive real-valued function f of one real variable x between a left endpoint a and a right endpoint b represents the area bounded by the lines x=a, x=b, the x-axis, and the curve defined by the graph of f.
		Improper integrals usually turn up when the range of the function to be integrated is infinite or, in the case of the Riemann integral, when the domain of the function is infinite.
		The Riemann-Stieltjes integral, an extension of the Riemann integral.

	Integral - Wikipédia
		An integral which can only be evaluated by considering it as the limit of integrals on successively larger and larger integrals is called an improper integral.
		Improper integrals usually turn up when the range of the function is infinite or, in the case of the Riemann integral, when the domain is infinite.
		The Lebesgue integral was created by Henri Lebesgue to integrate a wider class of functions and to prove very strong theorems about interchanging limits and integrals.

	Integral
		In particular, for a constant function, the integral is defined as its constant value times the measure of the region on which it is defined; in this basic case, the integral is just the area of a rectangle (in one dimension) or volume of a prism or cylinder (in two dimensions).
		The integral of a general function is then defined as the limit of the easily-calculated integrals of a sequence of simpler functions.
		Its integral is the size of the area bounded by the x-axis and the graph of a function, f(x); negative areas are possible.

	Henstock-Kurzweil integral - Wikipedia, the free encyclopedia
		In mathematics, the Henstock-Kurzweil integral, also known as the Denjoy integral (pronounce Denjua) and the Perron integral, is a possible definition of the integral of a function.
		Later, in 1957, the Czech mathematician Jaroslav Kurzweil discovered a new definition of this integral elegantly similar in nature to Riemann's original definition which he named the gauge integral; the theory was developed by Ralph Henstock.
		Another important property of the Henstock integral is that every function which is the derivative of some other function is gauge integrable, so a very strong form of the fundamental theorem of calculus holds.

	Denjoy
		Denjoy's dissertation, although not considered by him as among his greatest achievements when he looked back on his career in 1934, is now considered to contain some remarkable contributions.
		Denjoy was not a man lacking interests outside mathematics: on the contrary he was fascinated by topics such as philosophy, psychology, and social studies.
		Although Denjoy did not aspire to the political career of Herriot, who served in nine different cabinets and was premier of France three times, Denjoy's involvement with the Radical Party led to him serving as a town councillor for Montpellier in 1912, and as county councillor for Gers from 1920.

	Integral
		The integral value of a real number x is defined to be the largest integer which is less than or equal to x; it is often denoted by ⌊x⌋ and also called the floor function.
		In the integral calculus, the integral of a function is informally defined as the size of the area delimited by the x axis and the graph of the function.
		Details can be found under Riemann integral and Lebesgue integral.

		In addition, the longest chapter of the book is devoted to the theory of a two dimensional extension of the wide Denjoy integral.
