  • Embeddings of (proper) power graphs of finite groups 
    Doostabadi, A.; Farrokhi, D.G. (ДЗ "ЛНУ імені Тараса Шевченка", 2017)
    The (proper) power graph of a group is a graph whose vertex set is the set of all (nontrivial) elements of the group and two distinct vertices are adjacent if one is a power of the other. Various kinds of planarity of ...
  • Some properties of the nilradical and non-nilradical graphs over finite commutative ring Zn 
    Chandra, S.; Prakash, O.; Suthar, S. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    Let Zn be the finite commutative ring of residue classes modulo n with identity and Γ(Zn) be its zero-divisor graph. In this paper, we investigate some properties of nilradical graph, denoted by N(Zn) and non-nilradical ...
