Sous-anneaux de la forme D+I d'une K-algèbre intègre
The envelope of a subcategory in topology and group theory.
Universal mapping properties of some pseudovaluation domains and related quasilocal domains.
Elasticity of A + XB[X] when A ⊂ B is a minimal extension of integral domains
We investigate the elasticity of atomic domains of the form ℜ = A + XB[X], where X is an indeterminate, A is a local domain that is not a field, and A ⊂ B is a minimal extension of integral domains. We provide the exact value of the elasticity of ℜ in all cases depending the position of the maximal ideals of B. Then we investigate when such domains are half-factorial domains.
