In this paper we consider the structure of the class FGModS of full generalized models of a deductive system S from a universal-algebraic point of view, and the structure of the set of all the full generalized models of S on a fixed algebra A from the lattice-theoretical point of view;...
But how does this relate to the closure property under subtraction, the topic of our lesson? Open or close the box? We start with a set of numbers. This is like a the collection of common things in a box. We take any two of those numbers from the box, we subtract and see if ...
The unitary closure property of the prime varieties of associative algebras. We prove that every prime variety of associative algebras over an infinite field of characteristic p>0 is generated by either a unital algebra or a nilalge... - 《Siberian Mathematical Journal》...

Denote by F the q-shift polynomial ring consisting of elements, each of which is a polynomial in Qx, with coefficients which are polynomials in x over k⁡q. For a given operator L∈F, the Closure(L,Qx,x,q) calling sequence constructs a closure of L in the q-shift ...

We mention that the strati cation of the Lie algebra g implies the following "structural" property: if i ∈ IHs and j ∈ IHr , then C m ij ≠ ⇒ m ∈ IHs+r . (1.1) Notation 1.2. Let G be a step Carnot group (hence V = H ). From now on, we will set CHα := [C...
