The object of this paper is to introduce a new technique for showing that the number of labelled spanning trees of the complete bipartite graph K m, n is T(m, n) = m n − 1 n m − 1As an application, we use this technique to give a new proof of Cayley's formula T(n) = n n − 2, for the number of labelled spanning trees of the complete graph K n5 4 3 N 1 Of(x) = 2x 1 O AX) = _x11 Of(x) = 2x 11 o fx) = x 11 5 4 3 2 1 2 3 4 $\begingroup$ The second one is the right one (n2) = 2n $\endgroup$ – Moti Jan 25 '16 at 612 $\begingroup$ For me, I will do the your first suggested operation delay 2 samples then reversal, but the graph should be the bottom one $\endgroup$ –

N(n-1)/2 graph
N(n-1)/2 graph-$\frac{n(n1)}{2} = \binom{n}{2}$ is the number of ways to choose 2 unordered items from n distinct items In your case, you actually want to count how many unordered pair of vertices you have, since every such pair can be exactly one edge (in a simple complete graph)Therefore the maximum number of (distinct) edges in a graph with n vertices = (n × (n1))/2 Since this number is the maximum, it follows that m = a possible number of edges in a graph ≤ maximum number of edges in a graph n (n1) ≤ 2 Example graphs with the maximum # edges

3 min read Once you get beyond the basics of GraphQL, you'll likely hear people talk about the "N1 problem" This might seem scary, it does sound like O (N) notation The maximum number of edges a graph with N vertices can contain is X = N * (N – 1) / 2 The total number of graphs containing 0 edge and N vertices will be XC0 The total number of graphs containing 1 edge and N vertices will be XC1 And so on from a number of edges 1 to X with N vertices Hence, the total number of graphs that can be formed A series of discrete points exponentially decreasing from 5 to approaching 0 by a factor of 1/2 a_n = 5(1/2)^(n1) Assuming n in NN This is the discrete set of points a_n = 5/(2^(n1)) a_n is an infinite geometric sequence with first term (a_1) = 5 and common ratio (r) = 1/2 Since absr < 1 we know that the sequence converges ie a_n>0 as n> oo We have a series of discrete
