Translation for 'subgroup' from English to Italian

subgroup

sottogruppo {m}mat.

• A minimal normal subgroup of a group "G" is a nontrivial normal subgroup "N" of "G" such that the only proper subgroup of "N" that is normal in "G" is the trivial subgroup.
• A core-free subgroup is a subgroup whose normal core is the trivial subgroup. Equivalently, it is a subgroup that occurs as the isotropy subgroup of a transitive, faithful group action.
• In mathematics, the Langlands decomposition writes a parabolic subgroup "P" of a semisimple Lie group as a product [...] of a reductive subgroup "M", an abelian subgroup "A", and a nilpotent subgroup "N".
• In mathematical group theory, a subgroup of a group is termed a special abelian subgroup or SA-subgroup if the centralizer of any nonidentity element in the subgroup is precisely the subgroup [...].
• A maximal compact subgroup is a maximal subgroup amongst compact subgroups – a "maximal (compact subgroup)" – rather than being (alternate possible reading) a maximal subgroup that happens to be compact; which would probably be called a "compact (maximal subgroup)", but in any case is not the intended meaning (and in fact maximal proper subgroups are not in general compact).

• Finally, the Moy–Prasad subgroup [...] is defined as the subgroup of [...] generated by the subgroups [...] for [...] and the subgroup [...].
