    • n ab The eleventh month of the Jewish civil year, and the fifth of the ecclesiastical year, answering to a part of July and a part of August. In the Syriac calendar Ab is the last summer month.
    • n ab A prefix of Latin origin, denoting disjunction, separation, or departure, off, from, away, etc., as in abduct, abjure, etc. Before c and t, ab becomes (in Latin, and so in English, etc.) abs, as in abscond, abstain, etc.; before v and m, it becomes a, as in avert, amentia, etc. — In abbacinate and abbreviate, the prefix (reduced to a- in abridge, which see) is rather an assimilation of ad-.

Generalized entropy and Noether charge
V (A), and X 2 = X 2 V (A), and, with the additional data of an ob ject M ∈ Ab[A, V], abelian group homomorphisms ∂ , so that the diagram A-Set(X 0 , M ) ∂→ A-Set(X 1 , M ) ∂→ A-Set(X 2 , M ) is a fragment of a cochain complex in the abelian category Ab.
Abelian extensions of algebras in congruence-modular varieties
Another way to arrive at the same cochain complex is to apply the free functor from A-Set to Ab[A, V] to the A-sets X i V (Q), yielding ob jects Ci (Q, V) ∈ Ab[A, V].
Abelian extensions of algebras in congruence-modular varieties
That is, in that case, we can form the free ob ject in Ab[A, V ′ ] on A-set of generators X i V (Q), which we denote by Ci,V′ (Q, V), rather than the free ob ject in Ab[A, V] which we denoted by Ci (Q, V).
Abelian extensions of algebras in congruence-modular varieties
Recall that the wreath product of groups A and B , denoted A ≀ B , is the semidirect product (⊕AB ) ⋊ A, where ⊕AB is the direct sum of copies of B indexed by elements of A, and A acts via the “shift”, i.e. the left action of A on the index set A via left multiplication.

We will abbreviate both εab and εba to ε most of time since it is usually clear which one we are using, i.e., ε(u) = εab (u) if u ∈ Fa and ε(u) = εba(u) if u ∈ Fb .

Let φab and φba be defined as in 3.1, i.e., w = φab (u) if u ∈ Fa ( eEα−1 )|.

Again, we will and w ∈ Fb lie on a curve in the pencil |O eSα abbreviate both φab and φba to φ, i.e., φ(u) = φab (u) if u ∈ Fa and φ−→ w if w = φ(u).

Note that ˆΛ can be identified with the power series ring in the n noncommuting variables xi = ti − 1 and ˆΛab with the power series ring in n commuting variables xi = ti − 1. Λ (and also, ˆΛ, Λab , ˆΛab ) are rings with (anti)-involution given by g → ¯g = g−1 for g ∈ F .

Abelianization) If χab ∆ denotes the abelianization of χ∆ , then ∆ = log ∆b ∈ ˆΛab .

As there exists an F -link L with H1 (X ω a consequence every element ∆ of Λab satisfying (1’) and (2’) can be realized as the torsion polynomial of some boundary link. (c) (Duality) χ∆ = ¯χ∆ in ˆΛ/(cyclic), the quotient of ˆΛ by its subgroup generated by (ab − ba), for a, b ∈ ˆΛ.

We study 50 : 50 binary mixtures of N frictionless particles with a diameter ratio 1.4 [10,11] that interact pairwise via repulsive potentials: vab (r) = (ǫ/α) (1 − r/σab )α for r < σab and vab (r) = 0 for r > σab , where a, b label particles and σab = (σa + σb )/2.
