Consider a graph having each of its vertex belonging to a certain cycle. Consider the case when there are shared edges between the cycles. We can construct more that one graph in when a cycle shares it's two different edges with two different cycles. Hence, we can con construct a unique graph in every case given cycle matrix. For example, we have information from cycle matrix that a particular edge being part which all cycles. Consider the case when we have a graph with edges { a,b,c,d,e,f,g,h,i, j,k,x,y}, let edge {a,b,c,d,x} belongs to cycle 1, let {x,e,f,g,h,y} belong to cycle 2 and {y,i,j,k} belong to cycle 3. In this case, we can construct 2 graphs, both having the same cycle matrix:

6. Prove that the following graphs are connected: (a) The 3 vertex cycle: (b) The following 4 vertex graph: (c) K 7. An edge e of a connected graph G is called a cut edge if the graph G obtained by deleting that edge (V(G) V(G) and E(G) E(G) \<ej) is not connected. Prove that if G1 and G2 are connected simple graphs which are isomorphic and if G1 has a cut edge, then G2 also has a cut edge....

Let G=(V, E) be a connected graph with a weight w(e) associated with each edge e. Suppose G has n vertices and m edges. Let E’ be a given subset of the edges of E such that the edges of E’ do not form a cycle. (E’ is given as part of input.) Design an O(mlogn) time algorithm for finding a minimum spanning tree of G induced by E’. Prove that your algorithm indeed runs in O(mlogn) time. A minimum...

Question 1# (a) Let G be a connected graph and C a non-trivial circuit in G. Prove directly that if an edge e fa, b is removed from C then the subgraph S C G that remains is still connected. "Directly' means using only the definitions of the concepts involved, in this case connected' and 'circuit'. Hint: If z and y are vertices of G connected by path that includes e, is there an alternative path connecting x to y...
