In multi-dimensional system, it is hard to verify the various mixing properties, from topological mixing to strong specifications. Previously, in shift of finite type (SFT), we introduce corner-extendable conditions and hole-filling condition to establish some mixing theorems. The concepts can be expressed in terms of transition matrices and connecting operators. Based on these works, we are going to study the existence of natural measure in systems with strong mixing properties. In the cases that natural measure exists, the theory of Ruelle’s thermodynamic formalism applies. 官方說明文件#: NSC101-2115-M009-007-MY2 URI: http://hdl.handle.net/11536/98677https://www.grb.gov.tw/search/planDetail?id=2592136&docId=391856 顯示於類別： 研究計畫
