The principal investigator will study the existence of compact leaves in contact foliations of compact contact manifolds. The existence of these foliations was conjectured by Weinstein. Several special cases have been solved by this investigator and by other mathematicians. Lickorish surgical techniques will be used to investigate the three-dimensional version of the problem. Okumura's theory will be applied to the problem in the case of hypersurfaces with contact types in Kaehler manifolds. Diffeomorphism groups will also be studied. "Manifolds" are generalized surfaces. These may be filled with collections of lower dimensional "leaves." Such collections of leaves are called "foliations." The principal investigator will study leaves which do not wrap on continuously but actually close up. These are called in the literature, "compact leaves." Such are particularly important in applications to other sciences in that they represent, in a general sense, behavior which repeats indefinitely.

主要研究者将研究紧凑接触歧管的接触叶中的紧凑叶叶的存在。 这些叶子的存在是由温斯坦猜想的。 该调查员和其他数学家已经解决了一些特殊案例。 Lickorish手术技术将用于研究该问题的三维版本。 如果在Kaehler歧管中具有接触类型的Hypersurfaces，Okumura的理论将应用于该问题。 还将研究差异组。 “流形”是广义的表面。 这些可能充满了较低维的“叶子”的集合。 这样的叶子被称为“叶子”。 首席研究人员将研究不连续包裹但实际上关闭的叶子。 这些在文献中被称为“紧凑的叶子”。 这在应用于其他科学的应用中尤其重要，因为它们在一般意义上代表了无限期重复的行为。
