Uncertainty Quantification of Analytical Solutions for the Nonlinear Space and Time Fractional Order ϕ4$$ {\phi}^4 $$ Equation Under Fuzziness

Engineering Reports, Volume 8, Issue 7, July 2026.
Analytical fuzzy soliton solutions of a modified space–time fractional ϕ4$$ {\phi}^4 $$ model are derived using EHFM, capturing memory effects and uncertainty. Results reveal diverse wave structures and show how fractional order and fuzziness significantly influence soliton amplitude, localization, and propagation, with heightened sensitivity near the ...

Subvarieties of Abelian Varieties

, 2001
We discuss various constructions which allow one to embed a principally polarized abelian variety in the jacobian of a curve. Each of these gives representatives of multiples of the minimal cohomology class for curves which in turn produce subvarieties of higher dimension representing multiples of the minimal class.

Computing the Molecular Ground State Energy in a Restricted Active Space Using Quantum Annealing

Advanced Quantum Technologies, Volume 9, Issue 7, July 2026.
Can modern quantum annealers tackle realistic molecular problems? By combining XBK Hamiltonian mappings, next‐generation D‐Wave hardware, and advanced annealing protocols, significantly larger molecular instances become accessible with improved energy accuracy.

Axions, higher-groups, and emergent symmetry

Journal of High Energy Physics, 2022
Axions, periodic scalar fields coupled to gauge fields through the instanton density, have a rich variety of higher-form global symmetries. These include a two-form global symmetry, which measures the charge of axion strings.

On the field of rationality for an abelian variety [PDF]

Nagoya Mathematical Journal, 1972
The purpose of this paper is to prove the following two facts: IEvery generic polarized abelian variety of odd dimension has a model rational over its field of moduli.IINo generic principally polarized abelian variety of even dimension has a model rational over its field of moduli.

Proper moduli spaces of orthosymplectic complexes

Bulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.
Abstract We construct proper good moduli spaces for moduli stacks of Bridgeland semistable orthosymplectic complexes on a complex smooth projective variety, which we propose as a candidate for compactifying moduli spaces of principal bundles for the orthogonal and symplectic groups. We also prove some results on good moduli spaces of fixed‐point stacks

Wedderburn components, the index theorem and continuous Castelnuovo-Mumford regularity for semihomogeneous vector bundles

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2021
We study the property of continuous Castelnuovo-Mumford regularity, for semihomogeneous vector bundles over a given Abelian variety, which was formulated in A. Küronya and Y. Mustopa [Adv. Geom. 20 (2020), no. 3, 401-412].

On the Defining Equations of Abelian Varieties [PDF]

Nagoya Mathematical Journal, 1967
This article is a continuation and completion of our study in the previous one [1] in which we gave the defining equations of abelian varieties projectively embedded by theta functions of level three. These defining equations are nothing else the canonical generators of theta relations for theta functions with ⅓—characteristics.

Abelian threefolds with imaginary multiplication

Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract Let A$A$ be an abelian threefold defined over a number field K$K$ with potential multiplication by an imaginary quadratic field M$M$. Under mild assumptions on K$K$, if A$A$ has signature (2,1) and the multiplication by M$M$ is defined over KM$KM$, we attach to A$A$ an elliptic curve defined over K$K$ with potential complex multiplication by M$

The Néron component series of an abelian variety [PDF]

, 2010
We introduce the Néron component series of an abelian variety A over a complete discretely valued field. This is a power series in Z[[T]], which measures the behaviour of the number of components of the Néron model of A under tame ramification of the ...
