Extending partial isometries of antipodal graphs
Original language description
We prove EPPA (extension property for partial automorphisms) for all antipodal classes from Cherlin's list of metrically homogeneous graphs, thereby answering a question of Aranda et al. This paper should be seen as the first application of a new general method for proving EPPA which can bypass the lack of automorphism-preserving completions. It is done by combining the recent strengthening of the Herwig-Lascar theorem by Hubicka, Nesetril and the author with the ideas of the proof of EPPA for two-graphs by Evans et al.
