Quadratic Extensions of Flag-transitive Planes
European Journal of Combinatorics, 1999 A finite affine plane \(\pi\) of order \(q^2\) which has a subplane \(\pi_0\) of order \(q\) is called a quadratic extension of a flag-transitive plane if it admits a collineation group \(G\) which leaves \(\pi_0\) invariant, acts transitively on the flags of \(\pi_0\), and acts transitively on the lines of \(\pi\) intersecting \(\pi_0\) in precisely ...

International Journal of Mathematics and Mathematical Sciences, 2003 A correspondence between quartic étale algebras over a field and quadratic étale extensions of cubic étale algebras is set up and investigated. The basic constructions are laid out in general for sets with a profinite group action and for torsors, and ...

Generalized spinning particles on $${\mathcal {S}}^2$$ S 2 in accord with the Bianchi classification
European Physical Journal C: Particles and Fields, 2021 Motivated by recent studies of superconformal mechanics extended by spin degrees of freedom, we construct minimally superintegrable models of generalized spinning particles on $${\mathcal {S}}^2$$ S 2 , the internal degrees of freedom of which are ...

An extension of Gander’s result for quadratic equations
Journal of Computational and Applied Mathematics, 2010 In the study of iterative methods with high order of convergence, Gander provides a general expression for iterative methods with order of convergence at least three in the scalar case. Taking into account an extension of this result, we define a family of iterations in Banach spaces with R-order of convergence at least four for quadratic equations ...

Quadratic Extensions of Linearly Compact Fields [PDF]
Transactions of the American Mathematical Society, 1972 A group valuation is constructed on the norm factor group of a quadratic extension of a linearly compact field, and the norm factor group is explicitly computed as a valued group. Generalizations and applications of this structure theory are made to cyclic extensions of prime degree, to square (and pth power) factor groups, to generalized quaternion ...

Higher derivative three-form gauge theories and their supersymmetric extension
Journal of High Energy Physics, 2018 We investigate three-form gauge theories with higher derivative interactions and their supersymmetric extensions in four space-time dimensions. For the bosonic three-form gauge theories, we show that derivatives on the field strength of the 3-form gauge ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Solving Standard and Generalized EMPM Eigenvalue Problems: A QUBO Approach for the D-Wave Quantum Annealer [PDF]
EPJ Web of ConferencesWithin the Equation of Motion Phonon Method (EMPM) framework, we address the computation of the ground-state eigenpair of nuclear Hamiltonians by reformulating the eigenvalue problem as a Quadratic Unconstrained Binary Optimization (QUBO).

Application of k-means and Gaussian mixture model for classification of seismic activities in Istanbul [PDF]
Nonlinear Processes in Geophysics, 2012 Two unsupervised pattern recognition algorithms, k-means, and Gaussian mixture model (GMM) analyses have been applied to classify seismic events in the vicinity of Istanbul. Earthquakes, which are occurring at different seismicity rates and extensions of
