The complex case then follows from (a).
Continuity then finishes off the argument.
Theorem 3 may be interpreted as saying that $A=B$, but it must then be remembered that ......
Then $G$ has 10 normal subgroups and as many non-normal ones.
If $p=0$ then there are an additional $m$ arcs. [Note the article an.]
If $y$ is a solution, then $ay$ also solves (3) for all $a$ in $B$.
