Abstract
In this paper we introduce two new generalizations of Krull domains: -almost independent rings of Krull type (-almost IRKTs) and -almost generalized Krull domains (-AGKDs), neither of which need be integrally closed. We characterize them using certain types of -homogeneous ideals. To do this we introduce -almost super-homogeneous ideals and -almost super-SH domains. We prove that a domain is a -almost IRKT if and only if is a -almost super-SH domain and that a domain is a -AGKD if and only if is a type 1 -almost super-SH domain. Further, we study -almost factorial general-SH domains (-afg SH domains) and we prove that a domain is a -afg-SH domain if and only if is a -IRKT and an AGCD-domain.
