In this lesson, we are going to learn about graphs and the basic concepts of graph theory. We will also look at what is meant by isomorphism and homomorphism in graphs with a few examples.Updated: 11/05/2024 Defining Graphs AgraphG is triplet consisting of a set of edges E(G), a se...
IsomorphismNetworkImage visualizationThe graph theory is being used for representation in networks and chemical atomic structures very frequently. However, these days, uncertainties are imposed on such networks. Isomorphism in generalized fuzzy graphs has been introduced here to capture the similarity of ...
However, examples of non-isomorphic graphs whose adjacency matrices have the same characteristic polynomials have been found through computer search. Further, computation of characteristic polynomials for larger graphs is difficult and a computer is needed. In this paper different criteria, concept and ...

The second ingredient is a linear time algorithm for map isomorphism and Whitney equivalence. This part generalizes the seminal result of Hopcroft and Wong that graph isomorphism can be decided in linear time for planar graphs. 展开 关键词: graph isomorphism linear time algorithm map isomorphism ...
This was also the original context in which homomorphisms were studied (see e.g. [1,2]). But at several occasions the attention turned to combinatorial side thus displaying the emerging maturity of graph theory and (early) theoretical computer science. One should mention here pioneering works ...

Some classes (dense linear orders, for instance) are non-classifiable in general, but are classifiable when we consider only countable members. This paper explores such a notion for classes of computable structures by working out several examples. One motivation is to see whether some classes ...
simple graphs with the same numbers of vertices and edges, the problem of determining whether there exist correspondences between these vertices and edges such that there is an edge between two vertices in one graph if and only if there is an edge between the corresponding vertices in the other...
摘要: In this paper, we define soft quotient G-module, soft G-module homomorphism and soft kernel. Related to these definitions, we give some examples, homomorphism theorem and isomorphism theorems on Soft ...关键词: SoftG-module Soft QuotientG-module SoftG-module isomorphism theorems ...
