Unnormalised schemes

It was mentioned in earlier chapters that some of their results are inaccurate, that results are shown by methods which apply only to normalised schemes. Here we look at unnormalised schemes and how their properties can be deduced by normalising them. Because there are no obvious advantages in unnormalised schemes, they will be ignored in subsequent parts of this book. The reader impatient to get to the Design chapters can therefore skip this one. 

It is of interest to note that schemes containing the kernel [1,0,1], at c = 2, are in fact unnormalised schemes. Their continuity is exactly that determined by the joint spectral radius analysis of the kernel without any need for normalisation.
