an analytic function is a function that is locally given by a convergent power series. There exist both real analytic functions and complex analytic functions...

mathematics, smooth functions (also called infinitely differentiable functions) and analytic functions are two very important types of functions. One can easily...

branch of mathematics, analytic continuation is a technique to extend the domain of definition of a given analytic function. Analytic continuation often succeeds...

As a differentiable function of a complex variable is equal to the sum function given by its Taylor series (that is, it is analytic), complex analysis...

analytic function is often used interchangeably with "holomorphic function", the word "analytic" is defined in a broader sense to denote any function...

quasi-analytic class of functions is a generalization of the class of real analytic functions based upon the following fact: If f is an analytic function on...

analytic functions, unlike for complex analytic (that is, holomorphic) functions, these statements fail to hold. For example, consider the function f...

global analytic function is a generalization of the notion of an analytic function which allows for functions to have multiple branches. Global analytic functions...

holomorphic functions are analytic and vice versa. Among the corollaries of this theorem are the identity theorem that two holomorphic functions that agree...

the field dealing with the properties of these functions is called several complex variables (and analytic space), which the Mathematics Subject Classification...

In mathematics, every analytic function can be used for defining a matrix function that maps square matrices with complex entries to square matrices of...

The gamma function then is defined in the complex plane as the analytic continuation of this integral function: it is a meromorphic function which is holomorphic...

antiholomorphic functions (also called antianalytic functions) are a family of functions closely related to but distinct from holomorphic functions. A function of...

In SQL, a window function or analytic function is a function which uses values from one or multiple rows to return a value for each row. (This contrasts...

"closed-form function" and a "closed-form number" in the discussion of a "closed-form solution", discussed in (Chow 1999) and below. A closed-form or analytic solution...

example of a function that is differentiable but not locally Lipschitz continuous. The exponential function e x {\displaystyle e^{x}} is analytic, and hence...

result about analytic continuation of a complex-analytic function to a larger set. The idea is that one can extend a complex-analytic function (from here...

processing, an analytic signal is a complex-valued function that has no negative frequency components.  The real and imaginary parts of an analytic signal are...

The Schwarz function of a curve in the complex plane is an analytic function which maps the points of the curve to their complex conjugates. It can be...
