28 p, 759.2 KB The period of the limit cycle bifurcating from a persistent polycycle / Marín Pérez, David (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Queiroz, Lucas (Universidade Estadual Paulista. Instituto de Biociências, Letras e Ciências Exatas) ; Villadelprat Yagüe, Jordi (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We consider smooth families of planar polynomial vector fields {Xµ}µ∈Λ, where Λ is an open subset of R N , for which there is a hyperbolic polycycle Γ that is persistent (i. e. , such that none of the separatrix connections is broken along the family). [...]

27 p, 482.3 KB ∞ -operads as symmetric monoidal ∞ -categories / Haugseng, Rune (Norwegian University of Science and Technology) ; Kock, Joachim (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We use Lurie's symmetric monoidal envelope functor to give two new descriptions of ∞-operads: as certain symmetric monoidal ∞-categories whose underlying symmetric monoidal ∞-groupoids are free, and as certain symmetric monoidal ∞-categories equipped with a symmetric monoidal functor to finite sets (with disjoint union as tensor product). [...]

47 p, 693.7 KB Test vectors for archimedean period integrals / Humphries, Peter (University of Virginia (Charlottesville, Estats Units d'Amèrica)) ; Jo, Yeongseong (Ewha Womans University (Seül, Corea del Sud))
We study period integrals involving Whittaker functions associated to generic irreducible Casselman-Wallach representations of GLn(F), where F is an archimedean local field. Via the archimedean theory of newforms for GLn developed by the first author, we prove that newforms are weak test vectors for several period integrals, including the GLn × GLn Rankin-Selberg integral, the Flicker integral, and the Bump-Friedberg integral. [...]

24 p, 423.5 KB Classical and uniform exponents of multiplicative p -adic approximation / Bugeaud, Yann (Université de Strasbourg) ; Schleischitz, Johannes (Middle East Technical University (Güzelyurt, Turquia))
Let p be a prime number and ξ an irrational p-adic number. Its irrationality exponent µ(ξ) is the supremum of the real numbers µ for which the system of inequalities 0 < max{|x|, |y|} ≤ X, |yξ − x|p ≤ X−µ has a solution in integers x, y for arbitrarily large real number X. [...]

31 p, 491.7 KB Iwasawa theory of Hilbert modular forms for anticyclotomic extensions without Ihara's lemma / Xie, Bingyong (East China Normal University (Shanghai, Xina))
Following Bertolini and Darmon's method, with "Ihara's lemma" among other conditions Longo and Wang proved one divisibility of the Iwasawa main conjecture for Hilbert modular forms of weight 2 and general low even parallel weight in the anticyclotomic setting respectively. [...]

14 p, 387.3 KB Ordinary primes for some varieties with extra endomorphisms / Fité, Francesc (Universitat de Barcelona. Departament de Matemàtiques i Informàtica)
Let A be an abelian variety defined over a number field and of dimension g. When g ≤ 2, by the recent work of Sawin, we know the exact (nonzero) value of the density of the set of primes which are ordinary for A. [...]

31 p, 699.1 KB C ⋆ -algebras of higher-rank graphs from groups acting on buildings, and explicit computation of their K-theory / Mutter, Sam A. (Newcastle University. School of Mathematics, Statistics and Physics) ; Radu, Aura-Cristiana (Newcastle University. School of Mathematics, Statistics and Physics) ; Vdovina, Alina (Newcastle University. School of Mathematics, Statistics and Physics)
We unite elements of category theory, K-theory, and geometric group theory, by defining a class of groups called k-cube groups, which act freely and transitively on the product of k trees, for arbitrary k. [...]

20 p, 411.1 KB Oscillatory phenomena for higher-order fractional Laplacians / Abatangelo, Nicola (Università di Bologna. Dipartimento di Matematica) ; Jarohs, Sven (Goethe-Universität Frankfurt am Main. Institut für Mathematik)
We collect some peculiarities of higher-order fractional Laplacians (−∆)s , s > 1, with special attention to the range s ∈ (1, 2), which show their oscillatory nature. These include the failure of the polarization and P'olya-Szeg˝o inequalities and the explicit example of a domain with sign-changing first eigenfunction. [...]

Dipartimento di Matematica Tullio Levi-Civita) ; Cuadra, Juan (Universidad de Almería. Departamento de Matemáticas) ; Masut, Elisabetta (Università degli Studi di Padova. Dipartimento di Matematica Tullio Levi-Civita)
Let p be a prime number and q = pm, with m ≥ 1 if p 6= 2, 3 and m > 1 otherwise. Let Ω be any non-trivial twist for the complex group algebra of PSL2(q) arising from a 2-cocycle on an abelian subgroup of PSL2(q). [...]

21 p, 480.1 KB On metric and cohomological properties of Oeljeklaus-Toma manifolds / Angella, Daniele (Università degli Studi di Firenze. Dipartimento di Matematica e Informatica "Ulisse Dini") ; Dubickas, Arturas (Vilnius University (Lituània). Department of Mathematics and Informatics) ; Otiman, Alexandra (Università degli Studi di Firenze. Dipartimento di Matematica e Informatica "Ulisse Dini") ; Stelzig, Jonas (Ludwig-Maximilians-Universität München. Mathematisches Institut)
We study metric and cohomological properties of Oeljeklaus-Toma manifolds. In particular, we describe the structure of the double complex of differential forms and its Bott-Chern cohomology and we characterize the existence of pluriclosed (aka SKT) metrics in number-theoretic and cohomological terms. [...]
