2 J ul 1 99 8 The contraction of SU μ ( 2 ) and its differential structures to E κ ( 2 )

چکیده
The deformed double covering of E(2) group, denoted by Ẽκ(2), is obtained by contraction from the SUμ(2). The contraction procedure is then used for producing a new examples of differential calculi: 3D– left covariant calculus on both Ẽκ(2) and the deformed Euclidean group Eκ(2) and two different 4D–bicovariant calculi on Ẽκ(2) which correspond to the one 4D–bicovariant calculi on Eκ(2) described in Ref.[14]. ∗Supported by KBN grant 2 P03B 130 12

Saturation is (μ, κ)-transferable in T if and only if there is an expansion T1 of T with |T1| = |T | such that if M is a μ-saturated model of T1 and |M | ≥ κ then the reduct M ↾ L(T ) is κ-saturated. We characterize theories which are superstable without f.c.p., or without f.c.p. as, respectively those where saturation is (א0, λ)-transferable or (κ(T ), λ)-transferable for all λ. Further if for...
متن کامل1 8 N ov 1 99 3 Extensions of the Erdős - Rado Theorem
The actual version of 5.1 is slightly stronger. Here logκ is the least cardinal μ such that 2 ≥ κ, the exponentiation in 4.1 is ordinal exponentiation, and the products in 5.1 represent ordinal multiplication. For κ = ω, 3.1, 4.1, and 5.1 all follow from the known result ω1 → (α) 2 k for all α < ω1 and all k < ω (see ), so the uncountable case is the interesting one. The proofs make use of elem...
متن کاملVariable coordination of a chiral diphosphine containing an amidinium/NHC group within its backbone: μ-P,P', κ2-P,P' and κ3-P,C,P' coordination modes.
A diphosphine ligand (1·HPF(6)), which is a potential precursor to a PC(NHC)P pincer, with a backbone containing two phenylene groups and a central bicyclic 4-aza-2-azoniabicyclo[3.2.1]oct-2-ene unit has been synthesised and coordinated to Pd(II) and Pt(II) to give trans-[M(κ(2)-P,P'-)Cl(2)]PF(6) where M = Pd (2) or Pt (3a). Single-crystal structure determinations of 2 and 3a show the complexes...
متن کاملOn Distinguishing Quotients of Symmetric Groups
A study is carried out of the elementary theory of quotients of symmetric groups in a similar spirit to [10]. Apart from the trivial and alternating subgroups, the normal subgroups of the full symmetric group S(μ) on an infinite cardinal μ are all of the form Sκ(μ) = the subgroup consisting of elements whose support has cardinality < κ, for some κ ≤ μ. A many-sorted structure Mκλμ is defined wh...
متن کاملMixed sandwich thorium complexes incorporating bis(tri-isopropylsilyl)cyclooctatetraenyl and pentamethylcyclopentadienyl ligands: synthesis, structure and reactivity.
The Th(iv) mixed-sandwich halide complexes Th(COT(TIPS2))Cp*X (where COT(TIPS2) = 1,4-{Si(i)Pr(3)}(2)C(8)H(6), X = Cl, I) have been synthesised, and structurally characterised. When Th(COT(TIPS2))Cp*I is reduced in situ in the presence of CO(2), a mixture of dimeric carboxylate and oxalate complexes {Th(COT(TIPS2))Cp*}(2)(μ-κ(1):κ(2)-CO(3)) and {Th(COT(TIPS2))Cp*}(2)(μ-κ(2):κ(2)-C(2)O(4)) are f...
