27 Nov 2006: We begin with the derivation of a new asymptotic expan-sion, which has the property that the accuracy improves as the frequency of oscillationsincreases. ... We first present the Iserles and Nørsett expansion, to motivate the methodologybehind the new

24 Jan 2006: In a second step, an orthogonal matrix U issought that diagonalizes the new target set {W̃ T C1W̃ ,. , W̃. T C1W̃ }. This yields a separatingmatrix W = W̃ U ; see, for example, ... Com94] Pierre Comon, Independent component analysis, A new concept?,

26 Jul 2006: the requisite order of error. We now show that this new Levin-type method is equivalent to the originalLevin-type method. ... Thus. D̄(P D̄1W D̄G)D̄1 = P W G,. It follows that, where B2 = P D̄1W D̄G is the matrix associated with the new Levin-type
