- Abstract
Let n be a positive integer.We first discuss the n-phantom and n-Ext-phantom of morphisms in short exact sequence and pullback diagram of modules. Then, for a positive integer m ( m > n ), the relationship between Torn monomorphisms and Torn monomorphisms (Extn -epimorphisms and Extm-epimorphisms) are studied; The relationship between Torn -monomorphisms (Extn -epimorphisms) and their character morphisms has been investigated.
