“Voltage Graphs: An
Introduction”
By Tom McCourt
11am, Tuesday 14th October, 2008
Abstract:
In
topological graph theory a covering space (a generalization of a Riemann
surface) is an example of a mathematical structure that permits an economical
description of a graph and its imbedding.
The
details for constructing a covering space of a graph are efficiently encoded in
what is called a "voltage graph".
In
this talk we will focus on an elementary description and small investigation
into the world of voltage graphs.
However,
their connection to graph imbeddings and topology
will be left as a possible future topic for later journal club meetings.
The
setting for these talks is quite informal as we are all non-experts. We aim to spark a good discussion on an
interesting topic, so all are invited to attend. If you would like to contribute or have any
