Normal restriction in finite groups
Hung P. Tong-Viet
In this paper, we will prove some sufficient conditions for the solvability of groups.
Groups with normal restriction property
Hung P. Tong-Viet
Let G be a finite group. A subgroup M of G is said to be an NR-subgroup if, whenever K is normal in M, then K^G\cap M=K, where K^G is the normal closure of K in G. Using the Classi…
Character degree sums in finite nonsolvable groups
Kay Magaard, Hung P. Tong-Viet
Let N be a minimal normal nonabelian subgroup of a finite group G. We will show that there exists a nontrivial irreducible character of N of degree at least 5 which is extendible t…
Rank 3 permutation characters and maximal subgroups
Hung P. Tong-Viet
In this paper we classify all maximal subgroups M of a nearly simple primitive rank 3 group G of type L=Omega_{2m+1}(3), m > 3; acting on an L-orbit E of non-singular points of the…
