Determine if following graphs are bipartite
2. a) Determine whether the following graphs are isomorphic or not. If so write an isomorphism, if not explain why. 1 b 2 a 6 3 f d 5 4 e Graph A Graph B. b) Is the graph A bipartite. If not, find a vertex v such that A - v bipartite? c) Does the graph A have an Eulerian circuit? If not find an edge e such that A - e has an Eulerian circuit.
each of the following graphs has an Euler circuit. If it does have an Euler Determine whether such a circuit. If it does not have an Euler circuit, explain why you can find circuit, find be 100% sure. Ca au 2 (4) Find which of the following graphs are bipartite. Redraw the bipartite graphs so that their bipartite nature is evident. V2 5 니

Problem 8. (2+4+4 points each) A bipartite graph G = (V. E) is a graph whose vertices can be partitioned into two (disjoint) sets V1 and V2, such that every edge joins a vertex in V1 with a vertex in V2. This means no edges are within V1 or V2 (or symbolically: Vu, v E V1. {u, u} &E and Vu, v E V2.{u,v} &E). 8(a) Show that the complete graph K, is a bipartite graph. 8(b) Prove that no...
