Some Problems in Topology
by
Paul C. Kainen
Georgetown University (Dept. of Math. and Stat.)

We discuss crossing numbers, book thickness, spatially embedded graphs, connected-sum cycle bases, and the Colin de Verdiere invariant.

It is shown that for a spatially embedded graph, if every member of a connected-sum cycle basis is flat, then the embedded graph is flat.

We conjecture that there exists a non-flat embedded graph with a flat (non-connected-sum) basis.
