The Star graph $S_n$, $n\ge 3$, is the Cayley graph on the symmetric group$Sym_n$ generated by the set of transpositions $\{(12),(13),\ldots,(1n)\}$. Inthis work we study eigenfunctions of $S_n$ corresponding to the second largesteigenvalue $n-2$. For $n\ge 8$ and $n=3$, we find the minimum cardinality ofthe support of an eigenfunction of $S_n$ corresponding to the second largesteigenvalue and obtain a characterization of eigenfunctions with the minimumcardinality of the support.

Minimum supports of eigenfunctions with the second largest eigenvalue of the Star graph
