10 p, 277.5 KB Corrigendum and addendum to "Structure monoids of set-theoretic solutions of the Yang-Baxter equation" / Cedó, Ferran (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Jespers, Eric (rije Universiteit Brussel. Department of Mathematics) ; Verwimp, Charlotte (Vrije Universiteit Brussel. Department of Mathematics)
One of the results in our article which appeared in Publ. Mat. 65(2) (2021), 499-528,vis that the structure monoid M(X, r) of a left non-degenerate solution (X, r) of the Yang-Baxtervequation is a left semi-truss, in the sense of Brzezi'nski, with an additive structure monoid that is close to being a normal semigroup.

15 p, 364.2 KB Greedy approximation algorithms for sparse collections / Rey, Guillermo (Universidad Autónoma de Madrid. Departamento de Matemáticas)
We describe a greedy algorithm that approximates the Carleson constant of a collection of general sets. The approximation has a logarithmic loss in a general setting, but is optimal up to a constant with only mild geometric assumptions. [...]

44 p, 662.1 KB Holomorphic vector fields with a barycentric condition / Cerveau, Dominique (Université de Rennes 1) ; Déserti, Julie (Université d'Orléans) ; Lins Neto, Alcides (Instituto de Matemática Pura Aplicada (Brasil))
We study the p-tuples of holomorphic vector fields (X1, X2, . . . , Xp) satisfying the barycentric property Pk exp tXk = p · id, where exp tX denotes the flow of X.

7 p, 289.7 KB A remark on first integrals of vector fields / Belotto da Silva, André (Université de Paris, Institut de Mathématiques de Jussieu Paris Rive Gauche) ; Klimeš, Martin (University of Zagreb. Faculty of Electrical Engineering and Computing) ; Rebelo, Julio (Institut de Mathématiques de Toulouse) ; Reis, Helena (Universidade do Porto. Centro de Matemática)
We provide examples of vector fields on (C3 , 0) admitting a formal first integral but no holomorphic first integral. These examples are related to a question raised by D. Cerveau and motivated by the celebrated theorems of Malgrange and Mattei-Moussu.

14 p, 357.8 KB On generic flag varieties for odd spin groups / Karpenko, Nikita A. (University of Alberta)
For the spin group G = Spin2n+1 with arbitrary n, a generic G-torsor E over a field, and a parabolic subgroup P ⊂ G, we consider the generic flag variety E/P and describe its Chow ring modulo torsion. [...]

40 p, 527.5 KB Real forms of some Gizatullin surfaces and Koras-Russell threefolds / Blanc, Jérémy (Universität Basel. Departement Mathematik und Informatik) ; Bot, Anna (Universität Basel. Departement Mathematik und Informatik) ; Poloni, Pierre-Marie (Universität Basel. Departement Mathematik und Informatik)
We describe the real forms of Gizatullin surfaces of the form xy = p(z) and of Koras-Russell threefolds of the first kind. The former admit zero, two, three, four, or six isomorphism classes of real forms, depending on the degree and the symmetries of the polynomial p. [...]

We classify homogeneous CR submanifolds in complex hyperbolic spaces arising as orbits of a subgroup of the solvable part of the Iwasawa decomposition of the isometry group of the ambient space.

37 p, 487.8 KB On finite GK-dimensional Nichols algebras of diagonal type : rank 3 and Cartan type / Angiono, Ivan (Universidad Nacional de Córdoba) ; García Iglesias, Agustín (Universidad Nacional de Córdoba)
This paper contributes to the proof of the conjecture posed in [5], stating that a Nichols algebra of diagonal type with finite Gelfand-Kirillov dimension has a finite (generalized) root system. We prove the conjecture assuming that the rank is 3 or that the braiding is of Cartan type.

50 p, 590.0 KB An explicit formula for the second moment of Maass form symmetric square L-functions / Balkanova, Olga (Steklov Mathematical Institute (Moscou, Rússia)) ; Frolenkov, Dmitry (Steklov Mathematical Institute (Moscou, Rússia))
We prove an explicit formula for the second moment of symmetric square L-functions associated to Maass forms for the full modular group. In particular, we show how to express the considered second moment in terms of dual second moments of symmetric square L-functions associated to Maass cusp forms of levels 4, 16, and 64.

32 p, 706.4 KB An α-number characterization of Lp spaces on uniformly rectifiable sets / Azzam, Jonas (University of Edinburgh. School of Mathematics) ; Dąbrowski, Damian (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We give a characterization of Lp(σ) for uniformly rectifiable measures σ using Tolsa's α-numbers, by showing, for 1 < p < ∞ and f ∈ Lp(σ), that kfkLp(σ) ∼Z ∞0(αfσ(x, r) + |f|x,rασ(x, r))2drr12Lp(σ).
