  2. Domain (mathematical analysis) - Wikipedia

    en.wikipedia.org/wiki/Domain_(mathematical_analysis)

    In complex analysis, a complex domain (or simply domain) is any connected open subset of the complex plane C. For example, the entire complex plane is a domain, as is the open unit disk, the open upper half-plane, and so forth. Often, a complex domain serves as the domain of definition for a holomorphic function.

  3. Range of a function - Wikipedia

    en.wikipedia.org/wiki/Range_of_a_function

    is a function from domain X to codomain Y. The yellow oval inside Y is the image of . Sometimes "range" refers to the image and sometimes to the codomain. In mathematics, the range of a function may refer to either of two closely related concepts: the codomain of the function, or; the image of the function.

  4. Function (mathematics) - Wikipedia

    The domain of definition of such a function is the set of inputs for which the algorithm does not run forever. A fundamental theorem of computability theory is that there cannot exist an algorithm that takes an arbitrary general recursive function as input and tests whether 0 belongs to its domain of definition (see Halting problem).

  5. Domain of a function - Wikipedia

    en.wikipedia.org/wiki/Domain_of_a_function

    The set of points in the red oval X is the domain of f. Graph of the real-valued square root function, f(x) = √ x, whose domain consists of all nonnegative real numbers. In mathematics, the domain of a function is the set of inputs accepted by the function.

  6. Complex analysis - Wikipedia

    en.wikipedia.org/wiki/Complex_analysis

    The function on the larger domain is said to be analytically continued from its values on the smaller domain. This allows the extension of the definition of functions, such as the Riemann zeta function , which are initially defined in terms of infinite sums that converge only on limited domains to almost the entire complex plane.

  7. Ore condition - Wikipedia

    en.wikipedia.org/wiki/Ore_condition

    In mathematics, especially in the area of algebra known as ring theory, the Ore condition is a condition introduced by Øystein Ore, in connection with the question of extending beyond commutative rings the construction of a field of fractions, or more generally localization of a ring.

  8. Mathematical model - Wikipedia

    en.wikipedia.org/wiki/Mathematical_model

    The problem of rational behavior in this model then becomes a mathematical optimization problem, that is: (,, …,) subject to: =, =,, …,. This model has been used in a wide variety of economic contexts, such as in general equilibrium theory to show existence and Pareto efficiency of economic equilibria.

  9. Mathematics in Nepal - Wikipedia

    en.wikipedia.org/wiki/Mathematics_in_Nepal

    The history of mathematics in Nepal is inter-related with the history of mathematics in the Indian sub-continent. However, independent history of mathematics in Nepal also exists. The ancient Licchavi people developed a series of the system for measurement such as Kharika to measure land area and Kosh for measurement of distance.
