Symmetric Jordan Bi-semiderivations on Prime Rings

Abstract: In this paper, we investigate the structural properties of symmetric bi-semiderivations in the setting of prime and semiprime rings. By adapting classical derivation identities through the use of associated ω-homomorphisms, we obtain several characterization...

Grundy Locating-Hop Domination Sequences in Graphs

Abstract: Locating-hop domination refines hop domination by requiring vertices outside a hop dominating set to have nonempty and pairwise distinct distance-two signatures. Domination sequences, on the other hand, measure how long domination can be built through legal...
