| Outline of Final Research Achievements |
The following is the main part of the results obtained in this research. Firstly, as for the problem of determining whether every 5-connected projective planar triangulation is distance d m-extendable or not, we solved the d=4 case. Secondly, in 5-connected planar graphs with at most two non-triangular faces, we obtained the best threshold on distance matching extendability, which was not shown in the former research. Thirdly, it turned out that highly locally-connected star free graphs of even order have the property such that every matching in which the edges lie pairwise distance far apart is extendable.
