We consider European call options based on several underlying assets.
The number of assets then corresponds to the number of dimensions in the partial differential equation (PDE).
"The curse of dimensionality" makes this task increasingly difficult in higher dimensions
and it is necessary to find fast methods with very low memory requirements.
Reduced Basis Function (RBF) approximation is a promising candidate method.
With infinitely smooth RBFs the method can be spectrally accurate, meaning that the required
number of node points for a certain desired accuracy is relatively small.
The meshfree nature of the method makes it easy to use in higher dimensions and also
allows for adaptive node placement.
