Rigidity of quantum algebras

Journal of the London Mathematical Society, Volume 111, Issue 3, March 2025.
Abstract Given an associative C$\mathbb {C}$‐algebra A$A$, we call A$A$ strongly rigid if for any pair of finite subgroups of its automorphism groups G,H$G, H$, such that AG≅AH$A^G\cong A^H$, then G$G$ and H$H$ must be isomorphic. In this paper, we show that a large class of filtered quantizations are strongly rigid.

Gromov–Witten invariants of bielliptic surfaces

Journal of the London Mathematical Society, Volume 111, Issue 2, February 2025.
Abstract Bielliptic surfaces appear as a quotient of a product of two elliptic curves and were classified by Bagnera–Franchis. We give a concrete way of computing their GW‐invariants with point insertions using a floor diagram algorithm. Using the latter, we are able to prove the quasi‐modularity of their generating series by relating them to ...

Maximal commutative subrings and simplicity of Ore extensions

, 2012
The aim of this article is to describe necessary and sufficient conditions for simplicity of Ore extension rings, with an emphasis on differential polynomial rings. We show that a differential polynomial ring, R[x;id,\delta], is simple if and only if its

Review of conceptual and empirical approaches to characterize infiltration

Vadose Zone Journal, Volume 24, Issue 1, January/February 2025.
Abstract Infiltration regulates the movement and storage of water at the soil–atmosphere interface and is, therefore, a key component of many related physical and biogeochemical processes. Numerous studies have examined infiltration over the past two centuries.

Primitivity in skew Laurent polynomial rings and related rings

Mathematische Zeitschrift, 1993
Necessary and sufficient conditions for the primitivity of a skew Laurent polynomial ring over a commutative Noetherian ring are given, with explicit constructions of simple faithful modules. In two papers [Glasg. Math. J. 18, 93-97 (1977; Zbl 0347.16020) and ibid. 19, 79-85 (1978; Zbl 0374.16004)], the author gave sufficient conditions for primitivity

A temperature tipping point in hypoxic zone size

Limnology and Oceanography, Volume 69, Issue 12, Page 2954-2962, December 2024.
Abstract Temperature increases will have ubiquitous effects on aquatic food webs, from microbes to consumers, and affect the quality and quantity of carbon flows within and between water layers. A decline in the biological pump moving carbon from surface to lower layers is anticipated. We reviewed 37 years of data on hypoxic zone size and water quality

L${L}$‐functions of Kloosterman sheaves

Proceedings of the London Mathematical Society, Volume 129, Issue 5, November 2024.
Abstract In this article, we study a family of motives Mn+1k$\mathrm{M}_{n+1}^k$ associated with the symmetric power of Kloosterman sheaves constructed by Fresán, Sabbah, and Yu. They demonstrated that for n=1$n=1$, the L$L$‐functions of M2k$\mathrm{M}_{2}^k$ extend meromorphically to C$\mathbb {C}$ and satisfy the functional equations conjectured by ...

Classification conjectures for Leavitt path algebras

Bulletin of the London Mathematical Society, Volume 56, Issue 10, Page 3011-3060, October 2024.
Abstract The theory of Leavitt path algebras is intrinsically related, via graphs, to the theory of symbolic dynamics and C∗$C^*$‐algebras where the major classification programs have been a domain of intense research in the last 50 years. In this article, we gather together current lines of research in the classification of Leavitt path algebras ...

Cluster realisations of ıquantum$\imath {\rm quantum}$ groups of type AI

Proceedings of the London Mathematical Society, Volume 129, Issue 4, October 2024.
Abstract The ıquantum$\imath {\rm quantum}$ group Unı${\mathrm{U}^\imath _{n}}$ of type AIn$\textrm {AI}_n$ is a coideal subalgebra of the quantum group Uq(sln+1)$U_q(\mathfrak {sl}_{n+1})$, associated with the symmetric pair (sln+1,son+1)$(\mathfrak {sl}_{n+1},\mathfrak {so}_{n+1})$.
