The main effect under this project will be study of non- perturbative effects in quantum field theory using a variational approach for calculation of continuous fields approximated by their values on a discrete lattice of points. This is in constrast to the "Monte Carlo," random approach of other workers. The work will include approximations in the weak coupling limit and extension of supersymmetric work. Other topics include work on precision calculation of the magnetic moments of the electron and proton, some numerical "lattice string theory" work, and some work on time dependence of complex quantum mechanical systems. The work of this project should improve our understanding of field theories. It could lead to predictions for future experiments on the Superconducting Super Collider. Algorithms developed for the numerical work could have applications to other physics problems and, perhaps, to other scientific and engineering problems as well.

该项目的主要影响将是研究非 量子场论中的微扰效应 计算连续场的变分法 通过离散点网格上的值来近似。 这是在模拟过去的“蒙特卡罗”随机方法， 其他工人。 该工作将包括 弱耦合极限和超对称功的推广。 其他主题包括工作的精确计算 电子和质子的磁矩，一些数值 “格弦理论”的工作，以及一些关于时间依赖性的工作 复杂的量子力学系统。 这个项目的工作应该能增进我们对 场理论。 它可以预测未来 超导超级对撞机上的实验 算法 为数值工作开发的可以应用于 其他物理问题，也许，其他科学和 工程问题也是。
