     38  where [[latex($ \triangle _i $)]] is called a 'slope' for [[latex($ u_i ^n $)]], that is for the elements of [[latex($ \vec{u} $)]] in cell i on the nth time level. Using a linear function produces 2 extreme values of each cell, one on the left and on the right. These values are crucial in the MH scheme and their role will be presented shortly. A schematic of the situation is as follows:
