Abstrakt:	(4) Assume that both HT $e_{1}$ ht and HT $e_{2}$ ht create new ramification points, that is, both give Type II (b) extensions. It follows that HT $A E$ ht is a Type II extension. The definition of is inductive, done in parallel with the definition of the HT $_{V}^{i}$ ht . Suppose that HT $E_{1}$ ht and HT $E_{2}$ ht are of Type II over A. Then we will consider the following four sub-cases. The equivalence classes of the equivalence relation HT $E_{p}$ ht at the point p are called the I cones i at p. From now on, by I semilinear order i , we always mean a I lower i semilinear order. [Extracted from the article]
