Center node: "on planar greedy drawings of 3 connected planar graphs"
  Abstract: A graph drawing is $\textit{greedy}$ if, for every ordered pair of vertices $(x,y)$, there is a path from $x$ to $y$ such that the Euclidean distance to $y$ decreases monotonically at every vertex of the path. Greedy drawings support a simple geometric routing scheme, in which any node that has to send a packet to a destination "greedily" forwards the packet to any neighbor that is closer to the destination than itself, according to the Euclidean distance in the drawing. In a greedy drawing such a neighbor always exists and hence this routing scheme is guaranteed to succeed. #R##N#In 2004 Papadimitriou and Ratajczak stated two conjectures related to greedy drawings. The $\textit{greedy embedding conjecture}$ states that every $3$-connected planar graph admits a greedy drawing. The $\textit{convex greedy embedding conjecture}$ asserts that every $3$-connected planar graph admits a planar greedy drawing in which the faces are delimited by convex polygons. In 2008 the greedy embedding conjecture was settled in the positive by Leighton and Moitra. #R##N#In this paper we prove that every $3$-connected planar graph admits a $\textit{planar}$ greedy drawing. Apart from being a strengthening of Leighton and Moitra's result, this theorem constitutes a natural intermediate step towards a proof of the convex greedy embedding conjecture.
