Ancestor Approach to Number of Spanning Trees of Wheel Graph W n in Terms of Number of Spanning Trees of Fan Graph F n
An exclusive expression τ(W
n
) = 3τ(F
n
) –2τ(F
n–1) –2 for determining number of spanning trees of wheel graph Wn and a recurrence relation τ(W
n
)
= 3τ(W
n–1)–τ(W
n–2)+2 are derived by expressing τ(W
n
) into disjoint sets and expressing cardinality of each set in terms of τ(F
n
).
