Existence and Conjugacy of Hall Subgroups and Embedding of Pi-Subgroups
… $E\sb\pi$." If in addition any two Hall $\pi$-subgroups are conjugate in G, then we say that G satisfies $C\sb\pi$. If G satisfies $C\sb\pi$ and any $\pi$-subgroup of G is contained in some Hall $\pi$-subgroup, then G satisfies $D\sb\pi$.

Closure Operations on Subgroups
… research--if any--has been done on closures of subgroups. This thesis aims to give a comprehensive overview of closure operations on subgroups, much in the spirit of Epstein's paper. We begin with an introduction to the notion of closure operations on subgroups, as well as providing examples to …

Subgroups of the Torelli group
… group, I(Sg). <BR> <BR> We will study two subgroups of I(Sg). First we will look at the subgroup generated by all SIP-maps, SIP(Sg). We will show SIP(Sg) is not I(Sg) and is in fact an infinite index subgroup of I(Sg). We will also classify which SIP-maps are in the kernel of the Johnson …

Arithmetic Differential Subgroups of GL_{n}
… the study of a very special class of arithmetic subgroups of GL_n. We also introduce a set of functions, that we call Leibniz systems. These functions 'generate' some examples of the differential subgroups of GL_n. As a by-product we found more analogies between the ordinary differential operator …

Discrete and free subgroups of SL₂
In this thesis, we study finitely generated subgroups of the matrix group SL₂ (over various locally compact fields) which are both discrete and free. We first examine the existing literature on two- and three-generated subgroups of SL₂(R) and SL₂(C). Some such subgroups are known to be free, and …

Abusive parenting attitudes in parent training subgroups
The present study examines the abusive parenting attitudes of three subject populations (self-referred, abusive, and custody) in a parent training group. All subjects were administered the Adult-Adolescent Parenting Inventory (AAPI) before and after the parenting group. The hypothesis that all …

Rank 3 permuation characters and maximal subgroups
… field of G on the cosets G/H. Let H and K be subgroups of G. We say 1 \(\frac{G}{H}\) \(\leq\) 1\(\frac{G}{K}\)if 1 \(\frac{G}{K}\) \(\leq\) -1\(\frac{G}{H}\)is either 0 or a character of G. Also a finite group G is called nearly simple primitive rank 3 on E if there exists a quasi-simple …

Algorithms related to subgroups of the modular group
Classifying subgroups of the modular group PSL_2{Z} is a fundamental problem with applications to modular forms, in addition to its group-theoretic interest. While a lot of research has been done on the congruence subgroups of PSL_2{Z}, very little is known about noncongruence subgroups. The …
