三维(仿)切触度量和几乎(仿)余辛$(κ,μ)$ -空间的分类结果

Piotr Dacko

摘要:

综述了关于切触度量、几乎余辛流形和几乎Kenmotsu $(κ,μ)$ -流形的分类的已有结果。在三维情形下,详细描述了接触度量或几乎余辛$(κ,μ)$ -空间的结构.第二部分的文件地址三维仿接触度量和几乎仿辛$(κ,μ)$ -空间。对于$κ$的每一个可能值,得到了仿接触度量$(κ,μ)$ -空间和几乎仿辛$(κ,μ)$ -空间的局部分类.

英文摘要:

It is provided an overview of existed results concerning classification of contact metric, almost cosymplectic and almost Kenmotsu $(κ,μ)$-manifolds. In the case of dimension three it is described in full details structure of contact metric or almost cosymplectic $(κ,μ)$-spaces. The second part of the paper addresses three-dimensional paracontact metric and almost paracosymplectic $(κ,μ)$-spaces. There is obtained local classification of paracontact metric $(κ,μ)$-spaces, and almost paracosymplectic $(κ,μ)$-spaces, for every possible value of $κ$.
