Two of their attached data carry critical information: their zeros\, which govern the distributional behavior of underlying objects; and their central values\, which are related to invariants such as the class number of a field extension. \nWe will discuss the important conjectures\, one concerning the distribution of the zeros and one concerning the distribution of the central values\, and explain a general principle that any restricted result towards the first conjecture can be refined to show that most corresponding central values have the typical distribution predicted by the second conjecture. We will instantiate this general principle for a wide class of L-functions\, and provide a more detailed discussion in the case of L-functions attached to modular forms.

We extend to Dirichlet L-functions associated with arbitrary primitive characters a range of objects and properties鈥攊ncluding Eisenstein series and period functions鈥攖hat were originally introduced and studied by Lewis and Zagier\, and later by Bettin and Conrey in the case of the Riemann zeta function\, and more recently by Lewis and Zagier for odd real characters. These tools yield closed-form expressions for the moments of a measure defined via a weighted mean square of the L-function. These moments not only provide a complete characterization of the modulus of the L-function on the critical line\, but also imply an infinite number of non-trivial positivity conditions valid for all primitive characters\, real or not.

A combinatorial reciprocity theorem of Stanley鈥檚 tells us that evaluating the chromatic polynomial at -1 counts the number of acyclic orientations of the graph. Hanlon has proved an analogue of the aforementioned reciprocity theorem for the orbital chromatic polynomial\, which counts colorings that differ by a rotation or symmetry as the same. In this thesis we establish a reciprocity theorem for a new family of chromatic polynomials\, defined in terms of group representations\, that generalizes both the standard and the orbital chromatic polynomials.
