Cauchy product
Let and be two sequences of real or complex numbers for ( is the set of natural numbers containing zero). The Cauchy product is defined by:
(1) |
This is basically the convolution for two sequences. Therefore the product of two series , is given by:
(2) |
A sufficient condition for the resulting series to be absolutely convergent is that and both converge absolutely .
