Re-embedding structures of 4-connected projective-planar graphs
Yusuke Suzuki · Journal of Graph Theory · 2010
We identify the structures of 4-connected projective-planar graphs which generate their inequivalent embeddings on the projective plane, showing two series of graphs the number of whose inequivalent embeddings is held by O(n) with respect to the number of its vertices n. © 2010 Wiley Periodicals, Inc.
