On Generalized Derivations and Commutativity of Associative Rings [PDF]

open access: yes, 2020
Let be a ring with center Z(). A mapping f : → is said to be strong commutativity preserving (SCP) on if [f (x), f (y)] = [x, y] and is said to be strong anti-commutativity preserving (SACP) on if f (x) ◦ f (y) = x ◦ y for all x, y ∈. In the present

Commuting decomposition of Kn1,n2,...,nk through realization of the product A(G)A(GPk )

open access: yesSpecial Matrices, 2018
In this paper, we introduce the notion of perfect matching property for a k-partition of vertex set of given graph. We consider nontrivial graphs G and GPk , the k-complement of graph G with respect to a kpartition of V(G), to prove that A(G)A(GPk ) is ...

An Innovative Approach to Multi‐Valued Logic

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The current generation of computer systems operates on the principles of binary logic, which encompasses both logical and arithmetic operations. However, silicon technology has reached its peak performance, prompting researchers to explore alternative methods for enhancing computational efficiency. One such method is the adoption of Multi‐Valued Logic (

Measurement reduction for expectation values via fine-grained commutativity

open access: yes
We introduce a notion of commutativity between operators on a tensor product space, nominally Pauli strings on qubits, that interpolates between qubitwise commutativity and (full) commutativity.

Of Commutators and Jacobians [PDF]

open access: yes, 2021
I discuss the prescribed Jacobian equation $Ju=\det\nabla u=f$ for an unknown vector-function $u$, and the connection of this problem to the boundedness of commutators of multiplication operators with singular integrals in general, and with the Beurling operator in particular. A conjecture of T. Iwaniec regarding the solvability for general datum $f\in

Fused Collapsing for Wide BVH Construction

open access: yesComputer Graphics Forum, EarlyView.
Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...

Study of homoderivations on quotient near rings satisfying certain algebraic constraints

open access: yesМатематичні Студії
Let $N$ be a near ring and $P$, a prime ideal of $N$. In this paper, we define the notion of $P$-homoderivation in near rings. Also, we investigate the structure of quotient near ring $N/P$ via $P$-homoderivation satisfying some specific identities ...

Joint Distributions and Quantum Nonlocal Models

open access: yesAxioms, 2014
A standard result in quantum mechanics is this: if two observables are commuting then they have a classical joint distribution in every state. A converse is demonstrated here: If a classical joint distribution for the pair agrees with standard quantum ...

Weak commutativity between two isomorphic polycyclic groups [PDF]

open access: yes, 2014
An operator of weak commutativity between isomorphic groups, H and Hψ, was defined by Sidki as χ(H) = 〈HHψ | [h,hψ] = 1 for all h ∈ H〉, where ψ : h ↦ hψ for all h ∈ H defines an isomorphism. It is known that the operator χ preserves group properties such

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities

open access: yesComputer Graphics Forum, EarlyView.
Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...
