Theoretical research will continue on the study of interfaces and non-equilibrium systems driven to steady states by an external field. In an ongoing exploration of bulk singularities in driven systems, multi-point correlations will be investigated in models with a uniform drive, annealed random drives, repulsive interactions, and many species. Another area of study involves the interfaces in driven systems. Particularly, the effects of driving on roughening will be studied and selection mechanisms for the variety of bulk phases induced by different boundary conditions will be investigated. Additional studies will be undertaken on the interplay between bulk and interfacial fluctuations; morphological transitions due to curvature dominated closed membranes; and, conceptual questions associated with capillary wave theory. Long term projects include a thorough analysis of finite size effects and quenched impurities in driven systems, a wider class of competing dynamical models and applications to a variety of other related phenomena. %%%

理论研究将继续研究界面和非平衡系统通过外场驱动到稳态的系统。 在对驱动系统中批量奇异性的持续探索中，将在具有均匀驱动器，退火随机驱动器，排斥性相互作用和许多物种的模型中研究多点相关性。 研究的另一个领域涉及驱动系统中的界面。 特别是，将研究驾驶对粗糙度的影响，并研究将研究由不同边界条件引起的各种散装相的选择机制。 还将对批量和界面波动之间的相互作用进行其他研究；由于曲率占主导的闭合膜而引起的形态学转变；以及与毛细管波理论相关的概念问题。 长期项目包括对有限尺寸效应的彻底分析和驱动系统中的淬火杂质，更广泛的竞争动力模型以及针对其他相关现象的应用。 %%%
