Quadratic Poisson algebras on k[x, y, z]and their automorphisms

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
One of the important directions in modern mathematics is applications of Poisson structures and to various problems of mathematics and theoretical mechanics. These problems arise in dynamics of a rigid body, the celestial mechanics, the theory of curls,

Beyond Substitution—An Antipositionalist's Guide to Subtraction—

open access: yesPhilosophy and Phenomenological Research, EarlyView.
ABSTRACT Existing accounts of relations do not properly account for variably polyadic relations: they fail to capture the relationship between completions of the same relation by different numbers of relata. This paper develops a fully general account of such relations by adding an operation of subtraction to the antipositionalist theory of relations ...

Automorphisms and independent number of single nonzero component graph over a vector space

open access: yesOpen Mathematics
In this paper, we introduce a graph structure, called the single non-zero component graph Γ(V) ${\Gamma}\left(\mathbb{V}\right)$ , on a finite dimensional vector space V $\mathbb{V}$ .

The Picard group of Brauer-Severi varieties

open access: yesOpen Mathematics, 2018
In this paper, we provide explicit generators for the Picard groups of cyclic Brauer-Severi varieties defined over the base field. In particular,we provide such generators for all Brauer-Severi surfaces.

On the R-automorphisms of formal power series on several indeterminates and with coefficients over the ring R

open access: yesSelecciones Matemáticas, 2022
In this paper, we show a way to characterize the R-automorphisms of formal power series on several indeterminates and with coefficients over a commutative ring with identity, R.

Relative outer automorphisms of free groups [PDF]

open access: yes, 2011
Let $A_1,...,A_k$ be a system of free factors of $F_n$. The group of relative automorphisms $Aut(F_n;A_1,...,A_k)$ is the group given by the automorphisms of $F_n$ that restricted to each $A_i$ are conjugations by elements in $F_n$. The group of relative

Automorphisms of moduli spaces of symplectic bundle

open access: yes, 2011
Let X be an irreducible smooth complex projective curve of genus at least 3. Fix a line bundle L on X. Let M_{Sp}(L) be the moduli space of symplectic bundles (E, ExE ---> L) on X, with the symplectic form taking values in L.

Deterministic Theories

open access: yesPhilosophy and Phenomenological Research, EarlyView.
ABSTRACT Determinism is (roughly) the thesis that the past determines the future. But efforts to define it precisely have exposed deep methodological disagreements. Standard possible‐worlds formulations of determinism presuppose an “agreement” relation between worlds, but this relation can be understood in multiple ways, none of which is particularly ...

On the group of automorphisms of the algebra of plural numbers

open access: yesДифференциальная геометрия многообразий фигур, 2023
The algebra of dual numbers was first introduced by V. K. Clifford in 1873. The algebras of plural and dual numbers are analogous to the algebra of complex numbers. Dual numbers form an algebra, but not a field, because only dual numbers with a real part

Characterization of affine automorphisms and ortho-order automorphisms of quantum probabilistic maps [PDF]

open access: yes, 2013
In quantum mechanics, often it is important for the representation of quantum system to study the structure-preserving bijective maps of the quantum system. Such maps are also called isomorphisms or automorphisms.
