Signless Laplacian index conditions for doubly chorded cycles in graphs with given order
Signless Laplacian index conditions for doubly chorded cycles in graphs with given order
In this paper, we show that for a graph of order $n$, where $n\ge 5$, if the signless Laplacian index is larger than or equal to certain value depending on $n$, then the graph contains a doubly chorded cycle, where the chords incident to a common vertex, unless it is two specified graphs.
