We show a sufficient condition for a domain in to be a H
∞-domain of holomorphy. Furthermore if a domain has the Gleason property at a point and the projection of the n − 1th order generalized Shilov boundary does not coincide with Ω then is schlicht. We also give two examples of pseudoconvex domains in which the spectrum is non-schlicht and satisfy several
other interesting properties.

In this paper, we consider the problem of algorithmically constructing the left syzygy module for a finite system of elements
in an automaton monomial algebra. The class of automaton monomial algebras includes free associative algebras and finitely
presented algebras. In such algebras the left syzygy module for a finite system of elements is finitely generated. In general,
the left syzygy module in an automaton monomial algebra is not finitely generated. Nevertheless, the generators of the left
syzygy module have a recursive specification with the help of regular sets. This allows one to solve many algorithmic problems
in automaton monomial algebras. For example, one can solve linear equations, recognize the membership in a left ideal, and
recognize zero-divisors.

In this paper, we investigate the pseudo-amenability of semigroup algebra ? 1(S), where S is an inverse semigroup with uniformly locally finite idempotent set. In particular, we show that for a Brandt semigroup \(S={\mathcal{M}}^{0}(G,I)\), the pseudo-amenability of ? 1(S) is equivalent to the amenability of G. 相似文献

In this note an example of a finite lattice not having a finite basis of quasiidentities and an analogous example for algebras
of the type <1, 1> are indicated.

Let Ψ be a field, G a finite group of automorphisms of Ψ, and Φ the fixed field of G. Let H be a Hopf algebra over Ψ. For g ∈ G we define a Hopf algebra Hg which has the same underlying vector space as H and modified operations and show that the tensor product (over Ψ) ?g ∈ G Hg has a Φ-form. As a consequence we see that if n>0 is an integer and Φ is a field of characteristic zero or p>0 with (n,p)=1, then there is a finite dimensional Hopf algebra over Φ with antipode of order 2n. 相似文献

To a given basis on an -dimensional Hilbert space , we associate the algebra of all linear operators on having every as an eigenvector. So, is commutative, semisimple, and -dimensional. Given two algebras of this type, and , there is a natural algebraic isomorphism of and . We study the question: When does preserve the operator norm?

The paper deals with the following characteristics of random automaton graphs: the numbers of recurrent and nonrecurrent vertices, the number and dimensions of the components of strong connectivity, and the number of vertices attainable from a given one. Limit theorems are found for the distributions of these characteristics.Translated from Matematicheskie Zametki, Vol. 14, No. 1, pp. 133–141, July, 1973.In conclusion, the author wishes to express his gratitude to V.

It is shown that each Lie derivation on a reflexive algebra, whose lattice is completely distributive and commutative, can
be uniquely decomposed into the sum of a derivation and a linear mapping with image in the center of the algebra.
