对表面、界面和网络的静态和动态的研究将继续进行。具体的重点将放在以下领域：(1)熵在产生弹性和刚性的脆弱网络，如聚合物和凝胶中的作用。特别是，二维聚合物片提出了一个具有挑战性和潜在的富有成果的研究领域。将探讨膜和其他网络中的空间和库仑相互作用的影响。(2)动态生成的非线性在非平衡曲面上的作用。在膨胀和沉积过程中的生长过程中形成的尖头将被检查。同样，将研究受纵向驱动场影响的表面粗糙度。(3)磁体中杂质引起的畴壁钉钉和粗化以及线状缺陷。

Studies of static and dynamics of surfaces, interfaces, and networks will be continued. Specific focus will be on the following areas: (1) The role of entropy in generating elasticity and rigidity in tenuous networks such as polymers and gels. In particular, two dimensional polymeric sheets present a challenging and potentially fruitful area of study. The effects of steric and Coulomb interactions in membranes and other networks will be explored. (2) The role of dynamically generated nonlinearities on non-equilibrium surfaces. Formation of cusps during growth in expansion, and deposition processes will be examined. Similarly the roughness of a surface subject to longitudinal driving fields will be studied. (3) The pinning and roughening of domain walls and linear defects due to impurities in magnets.
