Self Maps and Margolis Killing Constructionin the Category of Spectra
《Chinese Quarterly Journal of Mathematics》1995年第4期32-40,共9页林金坤 
For a finite spectrum X, we prove the existence of a nonnilpotent element v inExitA(H*(X),H*(X))paralleled to the vanishing line which is a permanent cycle in the Adamsspectral sequence. We use this result to give a p...
