Where l −m is the number of components representing the last 20 % of the original mass.
the function f : Σ →Σ performing this redistribution is such that: In this formulation, we can consider the Caron ptransform and the PC-removal scheme as special cases, where the Caron p-transform is given by: and the PC-removal scheme by: where δ(F ) denotes the generalized Kronecker delta function.
