DESCRIPTION:Speaker: Alan Marcelo ARROYO GUEVARA\nAbstract: A straight-line
  drawing of a graph\, compared to a general drawing\, is not just more aes
 thetically appealing but\, from a practical point of view\, it is easier t
 o store it in a computer. This drives to a natural question: when can we c
 onvert a topological drawing into an equivalent geometric one?In 1988\, Th
 omassen completely answered this question for drawings in which every edge
  is crossed at most once (generalizing the well-known Farys Theorem). Thom
 assen's answer is by means of forbidding two drawings. Following Thomassen
 's result\,  I will talk about interesting classes of geometric graph draw
 ings than can be characterized in terms of forbidding a set of subdrawings
 \, and how this approach can bring new insights on tackling general graph 
 drawing problems.This talk is mainly based on joint collaborations with Ju
 lien Bensmail\, Dan McQuillan\, Bruce Richter\, Gelasio Salazar and Matthe
 w Sunohara.
