Publicacions matemàtiques
Publicacions Matemàtiques (ISSN: 0214-1493 print, 2014-4350 online) is a journal that publishes research quality articles about all fields of mathematics, and from time to time, also proceedings. This publication began to work in 1976 under the title Publicacions de la Secció de Matemàtiques (ISSN: 0210-2978 print, 2014-4369 online). In 1988, a new format and a new editorial board was introduced which gave rise to the second stage of the publication.

26 p, 512.9 KB Bilinear embedding for Schrödinger-type operators with complex coefficients / Carbonaro, Andrea (Università degli Studi di Genova. Dipartimento di Matematica) ; Dragicevic, Oliver (University of Ljubljana. Department of Mathematics)
We prove a variant of the so-called bilinear embedding theorem for operators in divergence form with complex coefficients and with nonnegative locally integrable potentials, subject to mixed boundary conditions, and acting on arbitrary open subsets of Rd.

49 p, 657.8 KB Constructing compacta from posets / Bartoš, Adam (Czech Academy of Sciences. Institute of Mathematics) ; Bice, Tristan (Czech Academy of Sciences. Institute of Mathematics) ; Vignati, Alessandro (Institut de Mathématiques de Jussieu - Paris Rive Gauche)
We develop a simple method of constructing topological spaces from countable posets with finite levels, one which applies to all second-countable T1 compacta. This results in a duality amenable to building such spaces from finite building blocks, essentially an abstract analogue of classical constructions defining compacta from progressively finer open covers.

7 p, 332.3 KB Uncountable interval of varieties of involution semigroups sharing a common semigroup variety reduct / Lee, Edmond W. H. (Nova Southeastern University (Fort Lauderdale, Estats Units d'Amèrica). Department of Mathematics)
A pair of involution semigroups sharing a common semigroup reduct of order eight is constructed with the property that the varieties they generate bound an interval that contains an uncountable chain. [...]

School of Mathematics) ; Ferrara, Maria (Università degli Studi della Campania "Luigi Vanvitelli". Dipartimento di Matematica e Fisica) ; Trombetti, Marco (Università degli Studi di Napoli "Federico II". Dipartimento di Matematica e Applicazioni "R. Caccioppoli")
If (X, r) is a finite non-degenerate set-theoretic solution of the Yang-Baxter equation, the additive group of the structure skew brace G(X, r) is an F C-group, i. e. a group whose elements have finitely many conjugates. [...]

Departamento de Análisis Matemático) ; Jung, Mingu (June E. Huh Center for Mathematical Challenges (Seül, Corea del Sud)) ; Mazzitelli, Martin (Universidad Nacional de Cuyo (Argentina)) ; Rodríguez, Jorge Tomas (Universidad Nacional del Centro de la Provincia de Buenos Aires. Departamento de Matemática)
We study the (uniform) strong subdifferentiability of norms of Banach spaces P(N X, Y ∗) of all continuous N-homogeneous polynomials and tensor products of Banach spaces, namely X⊗b π· · · ⊗b πX and ⊗b πs,NX. [...]

15 p, 441.3 KB Multisections of surface bundles and bundles over S1 / Moussard, Delphine (Institut de Mathématiques de Marseille)
A multisection is a decomposition of a manifold into 1-handlebodies, where each subcollection of the pieces intersects along a 1-handlebody except the global intersection, which is a closed surface. These generalizations of Heegaard splittings and Gay-Kirby trisections were introduced by Ben Aribi, Courte, Golla, and the author, who proved in particular that any 5-manifold admits sucha multisection.

38 p, 555.4 KB Porcupine-quotient graphs, the fourth primary color, and graded composition series of Leavitt path algebras / Vaš, Lia (Saint Joseph's University (Philadelphia, Estats Units d'Amèrica). Department of Mathematics)
If E is a directed graph, K is a field, and I is a graded ideal of the Leavitt path algebra LK(E), then I is completely determined by a pair (H, S) of two sets of vertices of E, called an admissible pair, and one writes I = I(H, S) in this case. [...]

Departamento de Matemática ; Nickel, Matthias (Johann Wolfgang Goethe-Universität. Institut für Mathematik) ; Roé Vellvé, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We study the shapes of all Newton-Okounkov bodies ∆v(D) of a given big divisor D on a surface S with respect to all rank 2 valuations v of K(S). We obtain upper bounds for, and in many cases we determine exactly, the possible numbers of vertices of the bodies ∆v(D). [...]

We investigate existence, Liouville-type theorems, and regularity results for the 3D stationary and incompressible fractional Navier-Stokes equations: in this setting the usual Laplacian is replaced by its fractional power (−∆) α 2 with 0 < α < 2. [...]

22 p, 442.4 KB Revisiting the Marcinkiewicz theorem for non-commutative maximal functions / Cadilhac, Leonard (Sorbonne Université Paris. Institut de Mathématiques de Jussieu) ; Ricard, Éric (Université de Caen Normandie)
We give an alternative proof of a Marcinkiewicz interpolation theorem for non-commutative maximal functions and positive maps and refine earlier versions of the statement. The main novelty is that it provides a substitute for the maximal function of a martingale in Lp, 1 < p 6 ∞, losing very little on numerical constants. [...]
