INTRINSIC PROPERTIES OF GRAPHS
EMBEDDED IN ℝ^{3}

ERICA FLAPAN, Editor in Chief of the Notices of the American Mathematical Society

^{3}. A natural
extension of knot theory is the study of embeddings of graphs in ℝ^{3}. However, in
contrast with knots, the structure of a graph can be complex, and this can affect
all of its embeddings. If every embedding of a graph has a particular property,
then we say that property is *intrinsic*
to the graph. For example, a graph is said to be *intrinsically knotted* if every embedding of the graph in ℝ^{3} contains a knot.
In this talk I will introduce intrinsic knotting and other intrinsic properties
of graphs, and present some open problems in the area.
