In theoretical computer science, the subgraph isomorphism problem is a computational task in which two graphs G and H are given as input, and one must determine whether G contains a subgraph that is isomorphic to ph isomorphism is a generalization of both the maximum clique problem and the problem of testing whether a graph contains a Hamiltonian cycle, and is therefore NP-complete.

An intriguing generalization of Eulerian walks was introduced by Messinger and Nowakowski in [19], as a variant of graph cleaning pro-cesses (see, for example, [2,20]). The reader is directed to [8] for an overview of graph cleaning and searching. Applying the Mycielskian repeatedly, starting with the one-edge graph, produces a sequence of graphs M i = μ(M i−1), sometimes called the Mycielski first few graphs in this sequence are the graph M 2 = K 2 with two vertices connected by an edge, the cycle graph M 3 = C 5, and the Grötzsch graph M 4 with 11 vertices and 20 edges..

First, we settle an open question of Demaine et al. by showing that Edge Hamiltonian Path is FPT parameterized by vertex cover, and that it also admits a cubic kernel.

As we cannot expect exact polynomial-time solutions, we use the approach of approximation algorithms. while some others give connection to the theory of hamiltonicity. In particular, we give a sufficient condition for the existence Author: Gábor Salamon. Fisher, McKenna, and Boyer showed that if a graph G is hamiltonian, then its Mycielski graph μ (G) is hamitonian.

In this note, it was shown that for a bipartite graph G, if its mycielski graph μ (G) is hamiltonian, then G has a Hamilton : Shuting Cheng, Dan Wang, Xiaoping Liu.

Cyclability is a natural generalization of hamiltonicity since clearly, if S = V (G), “ S is cyclable” is equivalent to “ G is Hamiltonian”. The readers can get corresponding results for hamiltonicity by setting S = V (G) in the results of this by: Charts.- Need to generalize the contemporary formulation of Lie's theory.- Isotopic generalization of the universal enveloping associative algebra.- Isotopic generalization of Lie's first, second, and third theorems.- Isotopic generalizations of enveloping algebras, Lie algebras, and Lie groups in classical and quantum.

Dirac's theorem () is a classical result of graph theory, stating that an n-vertex graph (n ≥ 3) is Hamiltonian if every vertex has degree at least n/2. Ore's theorem is a result in graph theory proved in by Norwegian mathematician Øystein gives a sufficient condition for a graph to be Hamiltonian, essentially stating that a graph with sufficiently many edges must contain a Hamilton ically, the theorem considers the sum of the degrees of pairs of non-adjacent vertices: if every such pair has a sum that at least equals.

Sudakov, Szabó and Vu [6] consider a generalization of Turán's Theorem. A graph G is said to be t-Turán if any subgraph of G containing no K t+1 has at most (1−1/t + o(1))e(G) edges where e(G.

This is a common generalization of the results obtained by Brandt et al. [Degree conditions for 2-factors, J. Graph Theory 24 (), –] and Yamashita [On degree sum conditions for long.

A generalization of Hamiltonicity is pancyclicity, the property that a graph contains a cycle of every possible length from 3 up to the order of the graph. Also, a cycle in a graph is said to be chorded if it contains an edge between 2 nonadjacent vertices on the : Tonya Miller.
