Token Graphs [PDF]

open access: yesGraphs and Combinatorics, 2011
For a graph $G$ and integer $k\geq1$, we define the token graph $F_k(G)$ to be the graph with vertex set all $k$-subsets of $V(G)$, where two vertices are adjacent in $F_k(G)$ whenever their symmetric difference is a pair of adjacent vertices in $G$.

Tokens and Tokenization

2020
The authors have carried out an examination of the status of tokens and tokenization in financial markets with regulatory problems, which lack proposals for solutions based on a generalized consensus. Overall, it seems to authors that cutting the Gordian knot of tokenization and tokens is the essential need to achieve a consensual and efficient ...

Token Shifting on Graphs

International Journal of Computer Mathematics: Computer Systems Theory, 2021
We investigate a new variation of a token reconfiguration problem on graphs using the cyclic shift operation. A colored or labeled token is placed on each vertex of a given graph, and a “move” consists in choosing a cycle in the graph and shifting tokens by one position along its edges.
