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.

Supersingular Abelian Varieties in Cryptology [PDF]

, 2002
. For certain security applications, including identity based encryption and short signature schemes, it is useful to have abelian varieties with security parameters that are neither too small nor too large.

Integral models of Shimura varieties with parahoric level structure, II

Forum of Mathematics, Pi
We construct integral models of Shimura varieties of abelian type with parahoric level structure over odd primes. These models are étale locally isomorphic to corresponding local models.

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

Spectral Analysis Implies Spectral Synthesis

Mathematics
In this paper we show that spectral analysis implies spectral synthesis for arbitrary varieties on locally compact Abelian groups that have no discrete subgroups of an infinite torsion-free rank.

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$

Null projections and noncommutative function theory in operator algebras

Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract We study projections in the bidual of a C∗$\mathrm{C}^*$‐algebra B$B$ that are null with respect to a subalgebra A$A$, that is, projections p∈B∗∗$p\in B^{**}$ satisfying |φ|(p)=0$|\varphi |(p)=0$ for every φ∈B∗$\varphi \in B^*$ annihilating A$A$. In the separable case, A$A$‐null projections are precisely the peak projections in the bidual of A$

GEOMETRICALLY SIMPLE QUASI-ABELIAN VARIETIES [PDF]

We define the geometric simpleness for toroidal groups. We give an example ofquasi-abelian variety which is geometrically simple, but not simple. We show that any quasi-abelian variety is isogenous to a product of geometrically simple quasi-abelian ...
