Topic: An infinitely differentiable function that is not analytic

  PlanetMath: analytic
Because of this equivalence, an analytic function in the complex case is often defined to be one that is holomorphic, instead of one having a Taylor series as above.
Although the two definitions are equivalent, it is not an easy matter to prove their equivalence, and a reader who does not yet have this result available will have to pay attention as to which definition of analytic is being used.
This is version 5 of analytic, born on 2001-12-28, modified 2004-10-24.

 Smooth function - Wikipedia, the free encyclopedia
For example, the exponential function is evidently smooth because the derivative of the exponential function is the exponential function itself.
Smooth functions with given closed support are used in the construction of smooth partitions of unity (see topology glossary for partition of unity); these are essential in the study of smooth manifolds, for example to show that Riemannian metrics can be defined globally starting from their local existence.
From what has just been said, partitions of unity don't apply to holomorphic functions; their different behaviour relative to existence and analytic continuation is one of the roots of sheaf theory.

 Analytic function   (Site not responding. Last check: 2007-10-22)
In mathematics, an analytic function is one that is locally given by a convergent power series.
Complex analysis teaches us that if a function f is differentiable in some open disk D centered at a point c in the complex field, then it necessarily has derivatives of all orders in that same open neighborhood, and the power series
That is an important respect in which complex functions are better-behaved than real functions; see an infinitely differentiable function that is not analytic.

Complex analysis teaches us that if a function f of one complex variable is differentiable in some open disk D centered at a point c in the complex field, then it necessarily has derivatives of all orders in that same open neighborhood, and the power series
A complex analytic function of several complex variables is defined to be analytic and holomorphic at a point if it is locally expandable (within a polydisk, a cartesian product of disks, centered at that point) as a convergent power series in the variables.
A real function of a real variable given locally by a power series is a real analytic function.

 Real Analysis
Infinite series, which are special sequences, are also studied at this point.
They are # a measurable set is ''almost'' an open set; # a measurable function is ''almost'' a continuous function; and # a convergent series is ''almost'' uniformly convergent.
An analysis is a critical evaluation, usually made by breaking a subject (either material or intellectual) down into its constituent parts, then describing the parts and their relationship to the whole.

Given a number of overlapping intervals on the line, bump functions can be constructed on each of them, and on semi-infiniteintervals (-∞, c] and [d,+∞) to cover the whole line, such that the sum of the functions is always1.

 More on Smoothness
A function is called C1 if it has a derivative that is a continuous function; such functions are also called continuously differentiable.
A function is called Cn for n ≥ 1 if it can be differentiated n times, with a continuous n-th derivative.
The smooth functions are therefore those that lie in the class Cn for all n.
