Matrix algebraic sets of infinite dimension [PDF]

Математичні Студії, 2012
Using multiplicative polynomials on algebras it is proved an analogue of Hilbert Nullstellensatz for the case of an infinite-dimensional real Banach space.

Hilbert Coefficients of Quadratic Algebras

Journal of Experimental Mathematics
If R = k[x1,...,xn]/I is a graded artinian algebra, then the length of k[x1,...,xn]/Is becomes a polynomial in s of degree n for large s. If we write this polynomial in the form ∑0<=i<=n (−1)i ei (s+n−i−1 choose n−i), then the ei's are called Hilbert coefficients of I.

MULTIPLIERS IN HILBERT ALGEBRAS

Journal of the Chungcheong Mathematical Society, 2012
In this paper, we introduce the concept of multiplier in a Hilbert algebra and obtained some properties of multipliers. Also, we introduce the simple multiplier and characterized the kernel of multipliers in Hilbert algebras.

Extensions of Effect Algebra Operations

Acta Polytechnica, 2011
We study the set of all positive linear operators densely defined in an infinite-dimensional complex Hilbert space. We equip this set with various effect algebraic operations making it a generalized effect algebra.

Miscellaneous Applications of Quons

Symmetry, Integrability and Geometry: Methods and Applications, 2007
This paper deals with quon algebras or deformed oscillator algebras, for which the deformation parameter is a root of unity. We show the interest of such algebras for fractional supersymmetric quantum mechanics, angular momentum theory and quantum ...

Effect Algebras of Positive Self-adjoint Operators Densely Defined on Hilbert Spaces

Acta Polytechnica, 2011
We show that (generalized) effect algebras may be suitable very simple and natural algebraic structures for sets of (unbounded) positive self-adjoint linear operators densely defined on an infinite-dimensional complex Hilbert space.
