从N-型映射到帐篷映射的半共轭

本文研究了从N-型映射到帐篷映射的半共轭.在一定的假设前提下,本文利用共轭方程给出了半共轭存在的必要条件,也给出了4个非单调的半共轭的精确表达式,并证明了它们均是无处可微的连续函数.

PHANTOM MAPS AND SPACES OFTHE SAME n-TYPE FOR ALL n

After reviewing the theory of phantom maps and SNT, the author gives several general results which relate the theory of phantom maps and SNT and which extend that of Harper and Roitberg.
