摘要
光滑流形通常需要考虑多个局部坐标系。在实 n 维空间这样的光滑流形上,我们通常在单个全局坐标系内工作。因此,定义偏微分算子并证明它们是超循环的并不难。然而,由于存在多个局部坐标系,在一般光滑流形上全局定义光滑函数的偏微分算子很难定义。我们引入了阿特拉斯光滑序列和阿特拉斯全形序列的概念,并用它们来研究流形上局部和全局定义的函数空间的超循环性和普遍性。我们重点研究作用于定义在光滑流形上的光滑函数的偏微分算子,同时也考虑复流形。1941 年,Seidel 和 Walsh [5] 证明,在定义于开放单位盘的全形函数空间上,某个序列是普遍的。我们在此利用所发展的思想将这一结果扩展到某些复流形。
Hypercyclicity and universality phenomena with atlas-smooth and atlas-holomorphic sequences
Smooth manifolds often require one to account for multiple local coordinate systems. On a smooth manifold like real n-dimensional space, we typically work within a single global coordinate system. Consequently, it is not hard to define partial differentiation operators, for example, and show that they are hypercyclic. However, defining a partial differentiation operator on smooth functions defined globally on general smooth manifolds is difficult due to the multiple local coordinate systems. We introduce the concepts of atlas-smooth and atlas-holomorphic sequences, which we use to study hypercyclicity and universality on spaces of functions defined both locally and globally on manifolds. We focus on partial differentiation operators acting on smooth functions defined on smooth manifolds, and we also consider complex manifolds as well. In 1941, Seidel and Walsh [5] showed that a certain sequence is universal on the space of holomorphic functions defined on the open unit disk. We use the ideas developed here to extend this result to certain complex manifolds.
