Abstract:
Some problems on extremal decomposition in families of nonoverlapping domains containing systems of biangles with free vertices are considered. In particular, a symmetrization result for systems of biangles with vertices on the unit circle is established. Cases where the problems considered reduce to some known problems on extremal decomposition are revealed. Bibl. – 8 titles.
Key words and phrases:extremal decomposition, biangle, redused module of biangle, trajectory, quadratic differential.
