Susumu Hirose, Akira Yasuhara

摘要:

讨论了嵌入3-球面的曲面上的一个正则同伦变形所诱导出的一个复同态的一个充要代数条件,并给出了该正则同伦所需的带符号移动次数的一个公式.

英文摘要:

A necessary and sufficient algebraic condition for a diffeomorphism over a surface embedded in the 3-sphere to be induced by a regular homotopic deformation is discussed, and a formula for the number of signed pass moves needed for this regular homotopy is given.
