On the Laplacian spectra of token graphs
Dalfó Simó, Cristina; Duque, Frank; Fabila Monroy, Ruy; Fiol Mora, Miquel Àngel; Huemer, Clemens; Trujillo Negrete, Ana Laura; Zaragoza Martínez, Francisco (Elsevier, 20210915)
Article
Open AccessWe study the Laplacian spectrum of token graphs, also called symmetric powers of graphs. The ktoken graph of a graph G is the graph whose vertices are the ksubsets of vertices from G, two of which being adjacent whenever ...

Open AccessWe study the Laplacian spectrum of token graphs, also called symmetric powers of graphs. The ktoken graph Fk(G) of a graph G is the graph whose vertices are the ksubsets of vertices from G, two of which being adjacent ... 
The connectivity of the flip graph of Hamiltonian paths of the grid graph
Duque, Frank; Fabila Monroy, Ruy; Flores Peñazola, David; Hidalgo Toscano, Carlos; Huemer, Clemens (2017)
Conference report
Open AccessLet Gn,m be the grid graph with n columns and m rows. Let Hn,m be the graph whose vertices are the Hamiltonian paths in Gn,m, where two vertices P1 and P2 are adjacent if we can obtain P2 from P1 by deleting an edge in P1 ...
