The eigenvalues are always connected to the characteristic polynomial of the matrix representation of a graph. In this paper, we discuss about the properties of adjacency matrix of the directed cyclic friendship graph, its cycle part is clockwise-oriented. By adding the values of the determinants ...
Is it possible to distinguish from the adjacency matrix of a graph if the whole system of points is interconnected, or if there are 2 or more subsystems, whcih have connections inside each subsystem but the subsystems are not connected to each other. Which properties does the adjacency matrix...
Let $\\\Delta$ be a bicolored quadriculated disk with black-to-white matrix $B_\\\Delta$. We show how to factor $B_\\\Delta = Lilde DU$, where $L$ and $U$ are lower and upper triangular matrices, $ilde D$ is obtained from a larger identity matrix by removing rows and colum...

An adjacency matrix is a matrix with rows and columns that is used to represent a simple labeled graph with the numbers 0 and 1 in the position of (VI, Vj), depending on whether the two Vi and Vj are adjacent. If an edge exists between vertex I or Vi and vertex j or Vj in...
NMF does not work for this matrix SVD works but does not give good features. Even after doing PCA and TSNE, the node features are not forming clusters according to communitites. We get only node features. Adjacency matrix gives only good node features NMF is allowed and gives good result...
Firstly, by using of BEC code[12] of the polyhexes, we give a algorithm and create a new BEC code which satisfies the condition of the hybrid system and by which we enumerate all the cases. Secondly, we use the adjacency matrix of polyhexes to get the corresponding adjacency matrix of...
Assumed to be undirected, simple, and connected are all of the graphs in this study, and adjacency matrix A serves as the associated matrix. In this paper we show that it is possible to relate a creation sequence for a type of cographs (we call it C-graphs). Those cographs can be ...
