They will continue the study of interfaces which divide co- existing phases of material, with the first two parts directed toward well defined and immediate goals. In the last part they propose problems which would require more time and thought, but applicable in a broader context of physics. (A) In an on-going exploration of systems with anisotropy, this part deals with both equilibrium and non-equilibrium crystal shapes. In particular, they will extend the study of effects of external forces (e.g., gravity) to include other types of fields and in three dimensions. For non-equilibria, they intend to investigate droplet shapes in a driven lattice gas system. (B) Within the context of dynamics, the interplay between bulk and interface fluctuations will be explored. (C) The long-term projects concern dynamics at first order transitions, effects of external forces on surface tension, and inclusion of curvature, torsion and Chern-Simons terms in studies of geometric objects beyond interfaces.

他们将继续研究划分共同体的界面， 材料的现有阶段，前两部分直接 朝着明确定义的近期目标迈进。 在最后一部分， 提出需要更多时间和思考的问题，但 适用于更广泛的物理学背景。 (A)在对各向异性系统的持续探索中， 第一部分讨论了平衡晶体和非平衡晶体 形状. 特别是，他们将扩大研究的影响， 外力（例如，重力），以包括其他类型的字段 和三维空间。 对于非均衡，他们打算 研究了驱动格子气系统中液滴形状。 (B)在动力学的背景下， 和界面波动进行研究。 (C)长期项目涉及一阶动力学 转变，外力对表面张力的影响，以及 曲率、挠率和Chern-Simons项在研究中应用 几何物体的界面之外。
