Abstract
This paper investigates some aspects of multigroups from Singh's perspective. It introduces a structured approach to analyzing the aspects of multigroups presented in this paper using dressed epsilon notation. We begin by defining the hierarchical decomposition of multisets, establishing that each r-level reference set in the hierarchical decomposition of a multiset over a group is itself a subgroup.We then present a fundamental characterization of multigroups by proving that a multisetA is a multigroup over a set X if and onlyif xy^(-1) ∈^p A,∀x∈^m A⟹p≥(m∧n). Additionally, we define the sets A^* and A_*and prove that both are subgroups of X using Singh’s dressed epsilon notation. Our work further investigates the algebraic properties of multigroupsand establishes criteria for commutativity. We also demonstrate that while the intersection of two multigroups is always a multigroup, their union does not necessarily inherit this structure. The concept of submultigroup is introduced to formalize the relationship between two multigroups. Finally, we establish the equivalence between certain multigroup properties, such as the symmetry of multisets based on product of elements and conjugate conditions.
