Abstract
Hedenmalm, Lindqvist, and Seip in 1997 [11] revitalized the modern study of Dirichletseries by defining the space H 2 and considering it as isometrically isomorphic to the Hardyspace of the infinite polytorus H 2 (T ∞ ). This allowed a new viewpoint to be applied toclassical theorems, including Carlson’s theorem about the integral in the mean of a Dirichletseries. Carlson’s theorem holds only for vertical lines in the right half plane, and cannot beextended to the boundary in full generality (as shown by Saksman and Seip in [14]). However,Carlson’s theorem can be shown to hold on the imaginary axis for a more restrictive class ofDirichlet series, and we shall do so.The main result contained in this dissertation is a generalized version of Carlson’s the-orem: given a Borel probability measure on the polytorus, a measure is constructed on theimaginary axis so that the integral in the mean is equal to the integral on the polytorus.Chapter 1 contains background material on Dirichlet series, including questions of con-vergence, the Bohr lift, and spaces of Dirichlet series. Chapter 2 is the statement and proofof the main result generalizing Carlson’s theorem.Finally, Chapter 3 is a small result about weighted spaces of Dirichlet series from workdone jointly with Houry Melkonian.
