The proof proceeds along the same lines as the proof of Theorem 5, but the details are more complicated.
For direct constructions along more classical lines, see .
Although these proofs run along similar lines, there are subtle adjustments necessary to fit the argument to each new situation.
Further results along these lines were obtained by Clark .
This paper, for the most part, continues this line of investigation.
Here c denotes a constant which can vary from line to line.
