Algebras with Variable Structural Constants and Their Applications

Abstract

We introduce a new class of algebras with variable structural constants and develop elements of the theory of monogenic functions in such algebras. Compatibility conditions for the structural functions are established. It is shown that the components of monogenic functions satisfy certain second-order partial differential equations with variable coefficients, and converse results are proved. This approach provides a constructive method for obtaining explicit solutions of such equations. Several illustrative examples are presented.

Jacobson radicals of Ore extensions

Let $R$ be a ring, $σ$ be an automorphism of $R$, and $D$ be a $σ$-derivation on $R$ with $Dσ=σD$. We will show that $J(R[x;σ,D])\subseteq A[x;σ,D]$ where $A$ is a collection of all leading coefficients of polynomials in $J(R[x;σ,D])$. In addition, we will prove that $J(R[x;σ,D])\cap R$ is nil if $σ$ is locally torsion and one of the following conditions is given: (1) $R$ is a PI-ring and $D$ is $q$-skew, (2) $R$ is an algebra over a field of characteristic $p>0$ and $D$ is a locally nilpotent derivation such that $σD=Dσ$. This answers partially an open question by Greenfeld, Smoktunowicz and Ziembowski.

Projective Differential Moment Invariants from the Viewpoint of Classical Invariant Theory

Polynomial first-order projective differential moment invariants are investigated. The main result establishes an exact correspondence between such moment invariants and symmetric polynomial multipoint relative projective differential invariants of weight $-1$. This correspondence describes each homogeneous component with respect to moment degree and allows previously obtained results on relative projective invariants to be used for systematic construction. It is also proved that passing from the formal algebra of moments to their integral definitions introduces no additional algebraic relations among the constructed invariants. For low moment degrees, the absence of nontrivial invariants of degrees $1$ and $2$ is established, and a complete description of degree $3$ invariants is obtained. The ten cubic differential moments are naturally identified with the coefficients of a ternary cubic, connecting the construction with classical invariant theory. In particular, the Aronhold invariants $S$ and $T$ yield projective differential moment invariants of degrees $4$ and $6$. One of the known moment invariants of Wang et al. is shown to be proportional to $S$. The algebra of polynomial moment invariants is proved not to be finitely generated. The field of rational moment invariants coincides with the field of fractions of the polynomial invariant algebra. For the explicit constructions, compact multipoint representations define the corresponding moment polynomials without requiring their full expansions. These representations provide a basis for algorithmic construction and software computation of the invariants.
