Prinjective Ringel-Hall Algebras for Posets of Finite Prinjective Type
《Acta Mathematica Sinica,English Series》2009年第7期1183-1190,共8页Justyna KOSAKOWSKA 
In the present paper we investigate prinjective Ringel-Hall algebras, for prinjective modules over incidence algebras of posers of finite prinjective type. Results we obtain are analogous to these, given by C. M. Ring...

A new concept Graded Finite Poset is proposed in this paper. Through discussing some basic properties of it, we come to that the direct product of graded finite posets is connected if and only if every graded finite p...
