p-adic analytic


Definition.

Let Cp be the field of complex p-adic numbers (http://planetmath.org/ComplexPAdicNumbers). Let U be a domain in Cp. A functionMathworldPlanetmath f:UCp is p-adic analyticPlanetmathPlanetmath if f has a Taylor seriesMathworldPlanetmath (with coefficients in Cp) about each point zU that converges to the function f in an open neighborhood of z.

For example, the p-adic exponential functionDlmfDlmfMathworldPlanetmath (http://planetmath.org/PAdicExponentialAndPAdicLogarithm) is analytic on its domain of definition:

U={zp:|z|p<1p1/(p-1)}.

The study of p-adic analytic functions is usually called p-adic analysisMathworldPlanetmath and it is very similar to complex analysis in many respects, although there are important differencesPlanetmathPlanetmath coming from the distinct topologies of and p.
