摘要:
It is a longstanding open problem in algebraic model theory to determine the model companions of the varieties of relative Stone algebras. Following Weispfenning's general model theory of Boolean products of structures we obtain various theories of Heyting algebras which are model and substructure complete. This works by adding only finitely many constant symbols to the language of Heyting algebras, one of which denoting a global dual atom. Thereby we especially obtain quantifier elimination for theories of atomless Post algebras of ordern.

摘要:
In [9] a local homology theory for Artinian modules over commutative rings, which is dual to the local cohomology theory for Noetherian modules, introduced and in [1] the main result of [9] extended. In this note we prove that the local homology modules of an Artinian module over a commutative ring (with identity) are Artinian.

摘要:
We show that the modular group γ3on the 27-dimensional exceptional domain admits only one multiplier system. At first we demonstrate that ¡aequals its own commutator subgroup by Jordan theoretic means, where the main tool is Hua's identity. Maaβ' description of all multiplier systems for the Siegel modular group then leads to the result. As a by-product we can describe the multiplier systems for the modular groups on the 10-dimensional boundary component and the half-spaces of quaternions.

摘要:
Let (E,Q) be a finite dimensional quadratic vector space over a finite field. For the natural representation -π of the isometry groupGof (E,Q) in the spaceL2(E) of all complex valued functions onE, we analyse when the intertwining algebra of π is generated by just one averaging operator.

摘要:
Some necessary and sufficient conditions are given for the ring of a Morita context to be a maximal order (resp. an Asano order, a Dedekind order, a Krull order).
