A function exhibiting this type of behaviour has been constructed in [9].
It became clear that the Riemann integral should be replaced by some other type of integral, better suited for dealing with limit processes.
Section 2 presents two L1-type characterizations.
Then A is an algebra of type II.
All of the action in creating Si+1 takes place in the individual cells of type 2 or 3.
It is a simple matter to remove all type 1 edges.
Therefore, the system (5) has a solution of the sought-for type.
for all f of the type specified in Theorem 4
