Abstract
In the present paper we describe Ext-projectives, Ext-injectives and almost
split sequences of category P-1(Lambda). We show that all almost split seq
uences of category P-1(Lambda) are exact. And we also give a correspondence
of projectives, injectives, and almost split sequences between categories
mod Lambda, P-1(Lambda) and some other categories.
