  • On properties of n-totally projective Abelian p-groups 
    Danchev, P.; Keef, P. (Український математичний журнал, 2012)
    We prove some properties of n-totally projective Abelian p-groups. Under certain additional conditions for the group structure, we obtain an equivalence between the notions of n-total projectivity and strong n-total ...
  • On strongly almost m-ω₁-pʷ⁺ⁿ-projective abelian p-groups 
    Danchev, P. (Algebra and Discrete Mathematics, 2015)
    For any non-negative integers man dn we define the class of strongly almost m-ω₁-pʷ⁺ⁿ-projective groups which properly encompasses the classes of strongly m-ω₁-pω⁺ⁿ-projective groups and strongly almost ω₁-pʷ⁺ⁿ-projective ...
  • On the Isomorphic Group Algebras of Isotype Subgroups of Warfield Abelian Groups 
    Danchev, P. (Український математичний вісник, 2006)
    A new class of global mixed Abelian groups, called W-groups, is defined. The following isomorphism theorem for commutative modular group algebras of such groups is proved: If G is a p-mixed μ-elementary W-group for some ...
