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.
