Divisionalization and symmetric product differentiation

Economic Theory Bulletin
AbstractI consider a standard two-stage game of divisionalization in which, in the first stage, two firms choose the number of divisions and, in the second stage, divisions compete independently à la Cournot. Two important assumptions are made. The creation of a division involves a fixed cost, and all divisions sell symmetrically differentiated goods ...

On symmetric products of continua

Topology and its Applications, 1999
For a given topological space \(X\) and for a positive integer \(n\) the set \({\mathcal F}_n (X) = \{A \subset X : A \) has at most \(n\) points\(\}\) is called the \(n\)-th symmetric product of \(X\). \textit{A. Illanes} [An. Inst. Mat., Univ. Nac. Autón. Méx.

OntOMat: Toward Ontology‐Based Product and Process Design Engineering and Optimization Solutions Fueling Circular Value Chains

Advanced Engineering Materials, EarlyView.
The OntOMat ontology establishes a structured framework for polymer matrix fiber reinforced composite materials, integrating manufacturing processes, characterization methods, and multiscale design through the VDI/VDE 3682 formalized process description standard.

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

On the distinguishing chromatic number of the Kronecker products of graphs

AKCE International Journal of Graphs and Combinatorics
In this paper, we investigate the distinguishing chromatic number of Kronecker product of paths, cycles, star graphs, symmetric trees, almost symmetric trees, and bisymmetric trees.

An Explicit Constitutive Reconstruction Framework for Mechanical Characterization of Miniaturized 3D‐Printed Specimens

Advanced Engineering Materials, EarlyView.
An explicit constitutive reconstruction framework enables accurate tensile characterization of miniaturized additively manufactured specimens using only the grip‐to‐grip displacement measurements. Progressive validation through self‐consistency, analytical comparison, and inverse finite element method (iFEM) benchmarking demonstrates constitutive ...

Generalized symmetries and deformations of symmetric product orbifolds

Journal of High Energy Physics
We construct generalized symmetries in two-dimensional symmetric product orbifold CFTs Sym N ( T $$ \mathcal{T} $$ ), for a generic seed CFT T $$ \mathcal{T} $$ .

Lightlike Hypersurfaces of a Semi-Riemannian Product Manifold and Quarter-Symmetric Nonmetric Connections

International Journal of Mathematics and Mathematical Sciences, 2012
We study lightlike hypersurfaces of a semi-Riemannian product manifold. We introduce a class of lightlike hypersurfaces called screen semi-invariant lightlike hypersurfaces and radical anti-invariant lightlike hypersurfaces.

Products of symmetric forms

Journal of Algebra, 1975
AbstractAssume r ⩾ 3 is a positive integer and let F be a field in which r! ≠ 0. By investigating the notion of formal multiplication of forms over F we are able to show that there exist indecomposable symmetric spaces of degree r over F of all positive dimensions.
