The primary winding 300 connects the collector of the transistor T1 to the positive power supply voltage. The secondary winding 310 is the output of the generator circuit and is applied to one of the electrodes of the reactor cell shown in FIG. 3. The feedback winding 320 is connected via diode ,D4, and R3 to the base of the transistor T1.

Following the approach of [6], we also study ,centralizers, of subgroups of pro-p PD3-groups. We produce the description below which must account additional cases (especially for pro-2 groups)that do not occurin the discrete case (see Theorem 3.1): Theorem. Let G be a pro-p PD3-group and H 6= 1 is a finitely generated subgroup of G with C G(H) 6= 1.

6 Sharpness of the 1 2 bound for 3 rewriteability The authors show sharpness of the 1 2 bound in two senses. 6.1 Pr 2(G) = 1 2 if and only if G=Z˘=S 3. 6.2 There exists a sequence fG ngof 3 rewriteable groups such that Pr 2(G n) !1 2 (from above). To nd this sequence of 3 rewriteable groups, the authors appeal to a result by Ito, which is as
