Function approximation, a central theme in numerical analysis and applied mathematics, seeks to represent complex functions through simpler or more computationally tractable forms. In this context ...

We deal with a method of enhanced convergence for the approximation of analytic functions. This method introduces conformal transformations in the approximation problems, in order to help extract the ...

When the logarithmic function is approximated by sequences of algebraic functions, similar questions can be posed as in the case of other similar problems. So, for example, it is interesting to ...

Polynomial approximation constitutes a fundamental framework in numerical analysis and applied mathematics, where complex functions are represented by simpler polynomial forms.

A new scheme for improving an approximation method of a probability density function is developed. The authors achieve the improvement of an approximation, whatever the starting approximate density.

Value function approximation or stopping time approximation: a comparison of two recent numerical methods for American option pricing using simulation and regression Lars Stentoft ...
