Some Problems in Topology

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.
