CHARACTERIZATION OF SOLVABLE GROUPS AND SOLVABLE RADICAL
International Journal of Algebra and Computation, 2013We give a survey of new characterizations of finite solvable groups and the solvable radical of an arbitrary finite group which were obtained over the past decade. We also discuss generalizations of these results to some classes of infinite groups and their analogues for Lie algebras. Some open problems are discussed as well.

A group \(G\) is called \(R^*\)-group if for all \(n>0\) and elements \(g\) and \(x_1,\dots,x_n\) the equation \(g^{x_1 }\cdots g^{x_n }=1\) implies \(g=1\). The following results are proved: (1) if \(G\) is an Abelian-by-nilpotent as well as nilpotent-by-Abelian \(R^*\)-group, then every partial order on \(G\) can be extented to a linear order; (2) if

Quadratic rational solvable groups
Journal of Algebra, 2012 A finite group G is quadratic rational if all its irreducible characters are either rational or quadratic. If G is a quadratic rational solvable group, we show that the prime divisors of |G| lie in {2,3,5,7,13}, and no prime can be removed from this list.

The authors say a group is homogeneous if any isomorphism between two of its finitely generated subgroups is induced by an automorphism. (In model theory there are also other versions of the concept of homogeneity; see the paper of \textit{B. I. Rose} and \textit{R. E. Woodrow} [Z. Math. Logik Grundlagen Math.
