Scalar extension of quadratic lattices II [PDF]

Nagoya Mathematical Journal, 1977
Let k be a totally real algebraic number field, the maximal order of k, and let L (resp. M) be a Z-lattice of a positive definite quadratic space U (resp. V) over the field Q of rational numbers. Suppose that there is an isometry σ from L onto M. We have shown that the assumption implies σ(L) = M in some cases in [2].

Torsion Subgroups of Elliptic Curves over Quadratic Extensions

, 1997
LetEbe an elliptic curve over Q. Observing certain relations between the torsion subgroups ofEandED, theD-quadratic twist ofE, we prove that the torsion subgroups ofEis stable for all but finitely many quadratic extensions. Moreover, using the result ofK.

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 ...

Solving Standard and Generalized EMPM Eigenvalue Problems: A QUBO Approach for the D-Wave Quantum Annealer [PDF]

EPJ Web of Conferences
Within 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).

Generalized trigonometric curve and its spline

Nihon Kikai Gakkai ronbunshu, 2021
On the extensions of the cubic Bézier curve with four control points, to connect multiple segments with required continuity has been strongly intended and for example, tangent and curvature continuity at the start and end points are guaranteed ...

Third Cohomology and Fusion Categories

, 2018
It was observed recently that for a fixed finite group $G$, the set of all Drinfeld centres of $G$ twisted by 3-cocycles form a group, the so-called group of modular extensions (of the representation category of $G$), which is isomorphic to the third ...

Round quadratic forms under algebraic extensions [PDF]

Pacific Journal of Mathematics, 1991
Pfister forms over fields are those anisotropic forms that remain round under any field extension. Here, round means that for any non-zero represented element x the isometry \(q\cong xq\) holds where q is the form under consideration. We investigate whether a similar characterization can be given for the round forms themselves.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Inductive graded rings, hyperfields and quadratic forms [PDF]

Categories and General Algebraic Structures with Applications
In [6] we developed a k-theory for the category of hyperbolic hyperfields (a category that contains a copy of the category of (pre)special groups): this construction extends, simultaneously, Milnor's k-theory ([20]) and Dickmann-Miraglia's k-theory ([13])

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
