Free subgroups in certain generalized triangle groups of type (2, m, 2)

A generalized triangle group is a group that can be presented in the form G = 〈 x, y | x = y = w(x, y) = 1 〉 where p, q, r ≥ 2 and w(x, y) is an element of the free product 〈 x, y | x = y = 1 〉 involving both x and y. Rosenberger has conjectured that every generalized triangle group G satisfies the Tits alternative. It is known that the conjecture holds except possibly when the triple (p, q, r)...

Near Frattini Subgroups of Certain Generalized Free Products of Groups

Let G = A ∗H B be the generalized free product of the groups A and B with the amalgamated subgroup H. Also, let λ(G) and ψ(G) represent the lower near Frattini subgroup of G and the near Frattini subgroup of G respectively. We show that G is ψ−free provided: (i) G is any ordinary free product of groups; (ii) G = A ∗H B and there exists an element c in G\H such thatH ∩H = 1; (iii) G = A ∗H B and...

Lifting Free Subgroups of PSL(2, R) to Free Groups

Let F = 〈a, b〉 be a rank two free group, let G = 〈A,B〉 be a two generator subgroup of PSL(2,R) and let ρ be a faithful representation of F with ρ(a) = A and ρ(b) = B. If G is discrete and free, many results about the primitive elements of G are proved using the geometry that G inherits from PSL(2,R), the group of orientation preserving isometries of the hyperbolic plane. Some of these results c...

On rational groups with Sylow 2-subgroups of nilpotency class at most 2

A finite group $G$ is called rational if all its irreducible complex characters are rational valued. In this paper we discuss about rational groups with Sylow 2-subgroups of nilpotency class at most 2 by imposing the solvability and nonsolvability assumption on $G$ and also via nilpotency and nonnilpotency assumption of $G$.

The Tits alternative for generalized triangle groups of type ( 3 , 4 , 2 )

A generalized triangle group is a group that can be presented in the form G = x, y | x p = y q = w(x, y) r = 1 where p, q, r ≥ 2 and w(x, y) is a cyclically reduced word of length at least 2 in the free product Z p * Z q = x, y | x p = y q = 1. Rosenberger has conjectured that every generalized triangle group G satisfies the Tits alternative. It is known that the conjecture holds except possibl...
