Barisan Modul Eksak dan Barisan Homomorfisma Modul Eksak

Abstract

This article explained  sequence exact of R-module and R-module homomorphism and their  relation.  Module is generalized of vector space V over field F.  If  M module over ring R, usually  denoted M R-module.  Module sequence is defined as homomorphism sequence from module to another module. 
R-Module sequence have exact property at a module, for example M_i, if  kernel function from M_i to M_i+1 same with  image function from M_i-1 to M_i.  The set of all R-module homomorphisms from M_i to M_i+1 will be denoted Hom_R(M_i,M_i+1).  Hom_R(M_i,M_i+1) is also module over ring which the same with  M_i and M_i+1.
