    Doctor of Philosophy (Ph.D.)

    I studied character theory of finite solvable groups

    specifically the character degree graph. The character degree graph consists of the set of vertices: the set of all primes that divide a character degree

    and the set of edges: two primes are adjacent if their product divides a character degree. I studied the case when the character degree graph has diameter three. I found that the graphs satisfied a very specific structure

    that the groups had exactly one normal non-abelian Sylow p-subgroup P

    and the prime p associated with that subgroup is known in the graph structure. Finally I found that if the graph of G/P' is considered

    that graph is disconnected and thus one of 6 known families of groups. It follows that the graphs with diameter three have Fitting height three.

    Character Degree Graphs of Finite Solvable Groups with Diameter three

    Let G be a solvable group and let Δ(G) be the character degree graph of G. The vertices of Δ(G) are the primes dividing character degrees of G and there is an edge between two primes if they divide a common character degree of G. In this paper

    we show that the group G has exactly one normal non-abelian Sylow p-subgroup and that prime is specified in the graph. The graph has two disjoint subgraphs that are themselves complete with the smaller subgraph having size n and the larger having size larger than 2^n. Further

    the group has Fitting height 3.

    Character Degree Graphs of Finite Solvable Groups with Diameter three

    Let G be a solvable group and let Δ(G) be the character degree graph of G. The vertices of Δ(G) are the primes dividing character degrees of G and there is an edge between two primes if they divide a common character degree of G. In this paper

    we show that the Taketa inequality dl(G) ≤ | cd(G)| holds when G is a solvable group whose degree graph Δ(G) has diameter 3.

    Looking for a position where I can use my analytical skills to have a positive impact in the world.
