Affine algebras at infinite distance limits in the Heterotic String

open access: yesJournal of High Energy Physics, 2023
We analyze the boundaries of the moduli spaces of compactifications of the heterotic string on T d , making particular emphasis on d = 2 and its F-theory dual. We compute the OPE algebras as we approach all the infinite distance limits that correspond to

A new model of the free monogenic digroup

open access: yesМатематичні Студії, 2023
It is well-known that one of open problems in the theory of Leibniz algebras is to find a suitable generalization of Lie’s third theorem which associates a (local) Lie group to any Lie algebra, real or complex. It turns out, this is related to finding an

Anomalous Spin‐Optical Helical Effect in Ti‐Based Kagome Metal

open access: yesAdvanced Materials, EarlyView.
The kagome lattice hosts diverse correlated quantum states, including elusive loop currents. We report spin‐handedness selective signals in CsTi3Bi5, termed the anomalous spin‐optical helical effect, surpassing conventional spin responses. Arising from light helicity coupled to spin‐orbital correlations, this effect provides a sensitive, indirect probe

Unsolid and fluid strong varieties of partial algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
A partial algebra 𝒜=(A;(fiA)i∈I) consists of a set A and an indexed set (fiA)i∈I of partial operations fiA:Ani⊸→A. Partial operations occur in the algebraic description of partial recursive functions and Turing machines. A pair of terms p≈q over the

Relative cellular algebras

open access: yes, 2019
In this paper we generalize cellular algebras by allowing different partial orderings relative to fixed idempotents. For these relative cellular algebras we classify and construct simple modules, and we obtain other characterizations in analogy to ...

Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings

open access: yesAdvanced Materials, EarlyView.
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external

A Note of W-algebra Realisations

open access: yes, 1992
We provide a general description of realisations of W--algebras in terms of smaller W--algebras and free fields. This is based on the definition of the W--algebra as the commutant of a set of screening charges.

Ultrafast Photocatalytic Wettability Switching in Substrate‐Interface Tailored Titanium Dioxide Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates ultrafast photocatalytic wettability switching in TiO2 thin films by tailoring substrate doping and interface oxides. Enhanced switching rates and hemiwicking effects are achieved through optimized material stacks and nanostructuring.

The automatic continuity for particular type of homomorphism nonassociative algebras [PDF]

open access: yesمجلة التربية والعلم, 2008
Rodriguez conjecture ensures the automatic continuity of a dense range homomorphism from a complete normed nonassociative algebra into another one with zero strong radical. Rodriguez conjecture still unsolved.

The derived category of surface algebras: the case of the torus with one boundary component

open access: yes, 2016
In this paper we refine the main result of a previous paper of the author with Grimeland on derived invariants of surface algebras. We restrict to the case where the surface is a torus with one boundary component and give an easily computable derived ...
