Extremal bipartite graphs with high girth
Let us denote by EX (m,n; {C4, . . . , C2t}) the family of bipartite graphs G with m and n vertices in its classes that contain no cycles of length less than or equal to 2t and have maximum size. In this paper the following question is proposed: does always such an extremal graph G contain a (2t + 2)-cycle? The answer is shown to be affirmative for t = 2, 3 or whenever m and n are large enough ...
متن کاملA construction of small regular bipartite graphs of girth 8
Let q be a prime a power and k an integer such that 3 ≤ k ≤ q. In this paper we present a method using Latin squares to construct adjacency matrices of k-regular bipartite graphs of girth 8 on 2(kq − q) vertices. Some of these graphs have the smallest number of vertices among the known regular graphs with girth 8.
متن کاملConstructions of small regular bipartite graphs of girth 6
In this article, some structures in the projective plane of order q are found which allow us to construct small k regular balanced bipartite graphs of girth 6 for all k ≤ q . When k = q , the order of these q-regular graphs is 2(q2−1); andwhen k ≤ q−1, the order of these k -regular graphs is 2(qk − 2). Moreover, the incidence matrix of a k -regular balanced bipartite graph of girth 6 having 2(q...
متن کاملOn λ_1-extremal non-regular graphs
Let G be a connected non-regular graph with n vertices, maximum degree ∆ and minimum degree δ, and let λ1 be the greatest eigenvalue of the adjacency matrix of G. In this paper, by studying the Perron vector of G, it is shown that type-I-a graphs and type-I-b (resp. type-II-a) graphs with some specified properties are not λ1-extremal graphs. Moreover, for each connected non-regular graph some l...
متن کاملRegular Graphs of given Girth
Graph theory is the study of mathematical structures called graphs. We define a graph as a pair (V,E), where V is a nonempty set, and E is a set of unordered pairs of elements of V . V is called the set of vertices of G, and E is the set of edges. Two vertices a and b are adjacent provided (a, b) ∈ E. If a pair of vertices is adjacent, the vertices are referred to as neighbors. We can represent...
