On rings with prime centers

International Journal of Mathematics and Mathematical Sciences, 1994
Let R be a ring, and let C denote the center of R. R is said to have a prime center if whenever ab belongs to C then a belongs to C or b belongs to C. The structure of certain classes of these rings is studied, along with the relation of the notion of ...

Shocks, superconvergence, and a stringy equivalence principle

Journal of High Energy Physics, 2020
We study propagation of a probe particle through a series of closely situated gravitational shocks. We argue that in any UV-complete theory of gravity the result does not depend on the shock ordering — in other words, coincident gravitational shocks ...

A Resource Efficient Ising Model‐Based Quantum Sudoku Solver

Software: Practice and Experience, EarlyView.
ABSTRACT Background Quantum algorithms exploit superposition and parallelism to address complex combinatorial problems, many of which fall into the non‐polynomial (NP) class. Sudoku, a widely known logic‐based puzzle, is proven to be NP‐complete and thus presents a suitable testbed for exploring quantum optimization approaches.

Information Dynamics and Learning in Complex Adaptive Systems: Toward a Transdisciplinary Framework

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This article develops a framework for understanding learning and adaptation in complex adaptive systems. Drawing from neuroscience, systems theory, information theory and quantum field theory, it examines how information processing, plasticity and systemic coherence emerge from distributed, nonlinear and feedback‐driven interactions. It argues

Some metric characterizations of commutativity in C*-algebras [PDF]

Surveys in Mathematics and its Applications
We study Le Page's theorem in the context of C*-algebras and obtain several characterizations of commutativity and centrality implied by identities or inequalities satisfied by the norm.

Lie Ideals and Homoderivations in Semiprime Rings

Mathematics
Let S be a 2-torsion free semiprime ring and U be a noncentral square-closed Lie ideal of S. An additive mapping ℏ on S is defined as a homoderivation if ℏ(ab)=ℏ(a)ℏ(b)+ℏ(a)b+aℏ(a) for all a,b∈S. In the present paper, we shall prove that ℏ is a commuting

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

Special 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 ...

Revisiting Ontology to Reshape Transgenerational Justice

Global Policy, EarlyView.
ABSTRACT This article develops a philosophical framework for understanding transgenerationality as a foundational concept for intergenerational justice. Drawing on social ontology and the philosophy of action, it introduces the notion of transgenerational civitas—a temporally extended community composed of past, present and future generations.

Computerized dynamic assessment of seriational thinking modifiability: Effects of mediation on seriation and readiness for math among kindergarten and grade 1 children

British Journal of Educational Psychology, EarlyView.
Abstract Background and Aims A vast body of theory and research highlights the operation of seriation as a prerequisite to mathematical thinking in young children. However, there is limited evidence that seriation interventions improve early years mathematics.

Fused Collapsing for Wide BVH Construction

Computer 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 ...
