| Research Abstract |
The following is the main part of the results obtained in this research. First a conjeture posed by Grunbaum and Nash-Williams turned out to be true if the toughness of the graph is 1. Next, on the triangulations of the plane, projective plane, torus and Klein bottle, many results concerning the problem "what kind of a matching is extendable to a perfect matching" are proved. In addition to the above, many results are obtained, as the proof of Lai et al.'s conjecture, a generalization of Jackson's theorem, and so on.
