- 요약A directed polymer is a Gibbs distribution given by an action that is the sum of a self-interaction term and an interaction with a random homogenous environment. This thesis investigates three main topics motivated by these statistical mechanics models in mostly continuous space. A common theme of this thesis is to establish results that apply for families of models without exact symmetries or explicit formulas.In Chapter 2 the concept of joint localization of directed polymers is introduced --- the phenomenon wherein the endpoint measures of polymers started at distinct starting points localize in common random regions whose length does not grow with the length of the polymer. We establish abstract conditions under which joint localization holds and prove that lattice directed polymers and Gaussian random walk directed polymers satisfy these conditions. We also establish the very strong disorder property in (1 + 1)-dimensional continuous space, discrete time polymers, implying single point localization for such models. In Chapter 3 and Chapter 4 we prove differentiability of the shape function for a variety of positive and zero temperature directed polymer models in continuous space. Our shearing method demonstrates differentiability of the shape function for a broad class of continuous settings, including semi-discrete polymers, fully continuous directed models at zero temperature, and continuous first passage percolation models, without exact symmetry. Finally, in Chapter 5 we study the ergodic properties of a semilinear stochastic partial differential equation on the half-line motivated by dynamics on infinite volume polymer measures. We prove a one force, one solution principle, or synchronization, in weighted $L.
