첫댓글The term analytic function is often used interchangeably with “holomorphic function”, although the word “analytic” is also used in a broader sense to describe any function (real, complex, or of more general type) that can be written as a convergent power series in a neighborhood of each point in its domain. The fact that the class of complex analytic functions coincides with the class of holomorphic functions is a major theorem in complex analysis. - Holomorphic function, Wikipedia.org(Eng) (link:http://en.wikipedia.org/wiki/Holomorphic_function)
