On a conjecture of Lovász on circle-representations of simple 4-regular planar graphs
Lovász conjectured that every connected 4-regular planar graph $G$ admits a <em>realization as a system of circles</em>, i.e., it can be drawn on the plane utilizing a set of circles, such that the vertices of $G$ correspond to the intersection and touching points of the circles and the...
