Weakly normal subgroup — In mathematics, in the field of group theory, a subgroup H of a group G is said to be weakly normal if whenever H^g leq N G(H), we have g in N G(H). Every pronormal subgroup is weakly normal.References* | year=2003 | journal=Journal of the… … Wikipedia
Normal form (abstract rewriting) — In abstract rewriting, a normal form is an element of the system which cannot be rewritten any further. Stated formally, for some reduction relation ⋅ → ⋅ over X a term t in X is a normal form if there does not exist a term t′ in X such … Wikipedia
Normal form (term rewriting) — In considering rewriting systems, a normal form is an element of the system which cannot be rewritten any further. Consider the basic term rewriting system with reduction rule ρ : g ( x , y ) → x . The term g ( g (4, 2), g (3, 1)) has the… … Wikipedia
Weakly interacting massive particles — In astrophysics, weakly interacting massive particles, or WIMPs, are hypothetical particles serving as one possible solution to the dark matter problem. These particles interact through the weak nuclear force and gravity, and possibly through… … Wikipedia
Weakly hyper-Woodin cardinal — In axiomatic set theory, weakly hyper Woodin cardinals are a kind of large cardinals. A cardinal κ is called weakly hyper Woodin if and only if for every set S there exists a normal measure U on κ such that the set {λ < κ | λ is … Wikipedia
C normal subgroup — In mathematics, in the field of group theory, a subgroup H of a group G is called c normal if there is a normal subgroup T of G such that HT = G and the intersection of H and T lies inside the normal core of H.For a weakly c normal subgroup, we… … Wikipedia
Jordan normal form — In linear algebra, a Jordan normal form (often called Jordan canonical form)[1] of a linear operator on a finite dimensional vector space is an upper triangular matrix of a particular form called Jordan matrix, representing the operator on some… … Wikipedia
