In this paper we show the expression of the nullity and nullity set of unicyclic graphs with vertices and girth , and characterize the unicyclic graphs with extremal nullity.doi:10.4236/am.2014.510156Shengbiao HuApplied MathematicsW. Zhu, T.-Z. Wu, S.-B. Hu, A note on the nullity of ...
Note that luw=0̸ when u is not adjacent to w. For u1,…,uk∈V(H), let Nu1⋯uk=Nu1(H)∩⋯∩Nuk(H). In the following we present a stability result for Berge-K3,t linear r-graphs. Theorem 2.1 Suppose that n≥r≥3 and H be a linear r-graphs with n vertices. Let u,...
Note that virtually all lines are red: for almost all combinations of all other inputs, the switch of problem structure from anarchy to hierarchy leads to a decrease in the portion of decisions by resolution. (See the paragraph on robustness below for additional comments on this property.) ...

.Notethatswitchingequivalenceisarelationofequivalence, and two switching equivalent graphs have the same nullities. A signed graph Γ is balanced if and only if Γ = (G, σ) ∼ (G, +) (see [1]). So the results on the nullity for simple graphs still hold for ...
∈Pp We also note the following lemma that is key in perturbative proofs such as ours of Theorem 1.4 or that of Irie–Marques–Neves [IMN18] for the generic existence of infinitely many hypersurfaces: Lemma 2.4 ([IMN18, Lemma 2.1]). — The p-width ωp(M, g) depends continuously on ...
Note that, for a mixed graph G˜, it is possible that EG˜=EG˜0 or EG˜=EG˜1. Hence, both oriented graphs and simple graphs can be seen as the special mixed graphs. Wong, Ma and Tian [23] provided a beautiful relation between the skew-rank of an oriented graph and the...
By the rank-nullity theorem, dim(span{v1,…,vn+1})=n−1. Moreover, observe that {v1,v3,v5,v6,…,vn+1} is an orthogonal basis. Let (ϵ1,…,ϵn+1)∈V be nonzero. For all i≥5, taking inner products with vi and ϵ1v1+⋯+ϵn+1vn+1, we obtain ϵi=0. For...
