The generic Markov cohomological Hall algebra is not spherically generated [PDF]

open access: yesRoyal Society Open Science
Let [Formula: see text] be the Markov quiver, and let [Formula: see text] be an infinitely mutable potential for [Formula: see text]. We calculate some low-degree refined Bogomol'nyi-Prasad-Sommerfield (BPS) invariants for the resulting Jacobi algebra ...

Observation of Body‐Centered‐Cubic Cu Nanocluster with Partial Cu(0) Character

open access: yesSmall Structures
The structure of nanoparticles is a key determinant of their material properties. The synthesis of non‐face‐centered‐cubic (FCC) Cu nanoclusters (NCs) with Cu(0) character is still challenging due to their instability. Herein, a Cu(0)‐containing Cu NC is

Nonvanishing for cubic L-functions

open access: yesForum of Mathematics, Sigma, 2021
We prove that there is a positive proportion of L-functions associated to cubic characters over $\mathbb F_q[T]$ that do not vanish at the critical point $s=1/2$.

Distortion Correction Algorithm for Complex Document Image Based on Multi-level TextDetection [PDF]

open access: yesJisuanji kexue, 2021
Document distortion correction is the basic step of document OCR(optical character recognition),which plays an important role in improving the accuracy of OCR.Document image distortion correction often depends on text extraction.However,most of the ...

Average value of the divisor class numbers of real cubic function fields

open access: yesOpen Mathematics, 2023
We compute an asymptotic formula for the divisor class numbers of real cubic function fields Km=k(m3){K}_{m}=k\left(\sqrt[3]{m}), where Fq{{\mathbb{F}}}_{q} is a finite field with qq elements, q≡1(mod3)q\equiv 1\hspace{0.3em}\left(\mathrm{mod}\hspace{0 ...

RESPONSE OF YIELD AND SOME TRAITS FOR TWO COTTON VARIETIES PLANT SPACES AND ANALYSIS OF CORRELATIONS AMONG YIELD AND ITS COMPONENTS TO DIRECT AND INDIRECT EFFECTS [PDF]

open access: yesMesopotamia Journal of Agriculture, 2010
The experiment include eight factorial treatments, represents the combinations between the two cotton varieties Lachata and SP8886 and four spaces between plants (15, 20, 25 and 30 cm), that carried out at Al-Hawyja, Karkuk Governorate during the season ...

On Abelian Automorphism Groups of Hypersurfaces [PDF]

open access: yes, 2021
Given integers $d\ge 3$ and $N\ge 3$. Let $G$ be a finite abelian group acting faithfully and linearly on a smooth hypersurface of degree $d$ in the complex projective space $\mathbb{P}^{N-1}$.

Superintegrability of Kontsevich matrix model

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Many eigenvalue matrix models possess a peculiar basis of observables that have explicitly calculable averages. This explicit calculability is a stronger feature than ordinary integrability, just like the cases of quadratic and Coulomb potentials are ...

Cubic preferences and the character admissibility problem [PDF]

open access: yesMathematical Social Sciences, 2019
In multiple-question referendum elections, the separability problem occurs when a voter's preferences on some questions or proposals depend on the predicted outcomes of others. The notion of separability formalizes the study of interdependence in multidimensional preferences, and the character admissibility problem deals with the construction of voter ...
