The Autonomous Interest of Society,ues are given when exactly one or exactly two limit cycles can be generated. For separatrix polygons with three or more saddle points similar criteria are given to ensure the generation of at least one, two, or more (till n for a n sided polygon) limit cycles.

,On Bäcklund transformations and solutions to the 2+1 and 3+1 - dimensional sine — Gordon equation, time of the area between three line solitons moving in the XY-plane and of the volume between four plane solitons moving in the XYZ-space. The latter result which is a necessary condition for plane solitons is believed to be new.
