Mathematics Seminars for the week of November 29, 2004
Colloquium
Thursday, 3:30, in VinH 16Professor Vic Reiner
will speak on
"The critical group of a graph"
Since the work of Kirchoff in 1846 on electrical networks, it was
known that the spanning trees in a graph (= node-edge network) are counted by
a certain determinant. More recently people have looked at a finite abelian
group, called the ``critical group'', whose order is this number of spanning
trees. This group turns out to have many beautiful equivalent reformulations,
which we will discuss. We will also discuss some of the few general results
known relating the structure of the group to the structure of the graph, along
with its analogy to the Picard group or Jacobian variety of a Riemann
surface.
