The k-tok en graph F_k(G)of a graph G is the graph\nwhose vertices are the k-subsets of vertices from G\, two of which\nbeing adjacent whenever their symmetri c difference is a pair of\nadjacent vertices in G. In this talk\, we give a relationship between\nthe Laplacian spectra of any two token graphs of a given graph.\n DTSTAMP:20250524T054345Z END:VEVENT END:VCALENDAR
