... (1), we improve some recent results of Nikiforov [16] regarding the spectral radius of a subgraph of a regular graph. We also investigate the spectral radius of a graph obtained from a regular ... the spectral radius of a general (not necessarily regular) graph G and that of a subgraph of G, see [16]. 2 The spectral radius and the maximum degree The following theorem is...

... eρ + ,andeρ + ∈ E; (ii) λ + e =(λe) + . Proof. (i) Since we assume that the set of all idempotents E of the semigroup S forms a semilattice, all idempotents of S commute. Hence, λ + e =(λe) + e = ... set P (S) of all right translations) of the semigroup S forms a semigroup under the composition of mappings. By the translational hull of S, we mean a subsemigroup Ω(S) consisting...
