a 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...

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...

power series. Quasi-analytic function: not analytic, but still locally determined by its derivatives at a point. Differentiable function: Has a derivative...

In mathematics and statistics, the quasi-arithmetic mean or generalised f-mean or Kolmogorov-Nagumo-de Finetti mean is one generalisation of the more...

Quasi-Newton methods are methods used to find either zeroes or local maxima and minima of functions, as an alternative to Newton's method. They can be...

p-adic analytic manifolds, rigid analytic spaces admit meaningful notions of analytic continuation and connectedness. The basic rigid analytic object...
