Signed graphs connected with the root lattice
For any base of the root lattice (An) we can construct a signed graph. A signed graph is one whose edges are signed by +1 or -1. A signed graph is balanced if and only if its vertex set can be divided into two sets-either of which may be empty–so that ...

Singed Total Domatic Number of a Graph [PDF]
The maximum number of functions in a signed total dominating family on G is the signed total domatic number of G. In this paper, some properties related signed total domatic number and signed total domination number of a graph are studied and found the ...

ON THE SIGNED MATCHINGS OF GRAPHS [PDF]
For a graph $G$ and any $v\in V(G)$, $E_{G}(v)$ is the set of all edges incident with $v$. A function $f:E(G)\rightarrow \{-1,1\}$ is called a signed matching of $G$ if $\sum_{e\in E(v)}f(e) \leq 1$ for every $ {v\in V(G)}$. For a signed matching $x$, set $x(E(G))=\sum_{e\in E(G))}x(e)$.

Learning Embedding for Signed Network in Social Media with Hierarchical Graph Pooling
Signed network embedding concentrates on learning fixed-length representations for nodes in signed networks with positive and negative links, which contributes to many downstream tasks in social media, such as link prediction.

SIGNED GENERALIZED PETERSEN GRAPH AND ITS CHARACTERISTIC POLYNOMIAL [PDF]
Let G^s be a signed graph, where G = (V;E) is the underlying simple graph and s : E(G) to {+, -} is the sign function on E(G). In this paper, we obtain k-th signed spectral moment and k-th signed Laplacian spectral moment of Gs together with coefficients ...
