Publicacions matemàtiques
Publicacions Matemàtiques (ISSN: 0214-1493 imprès, 2014-4350 en línia) és una revista que publica articles de qualitat de recerca de tots els camps de les matemàtiques i, de tant en quant, també actes de congressos. Aquesta revista va començar l'any 1976 amb el títol de Publicacions de la Secció de Matemàtiques (ISSN: 0210-2978 imprès, 2014-4369 en línia). L'any 1988 va introduir un nou format i comitè editorial que van donar lloc a la segona etapa d'aquesta revista.

Non-uniformly local tent spaces / Amenta, Alex (Université Paris-Sud. Laboratoire de Mathématiques) ; Kemppainen, Mikko (University of Helsinki. Department of Mathematics and Statistics)
We develop a theory of `non-uniformly local' tent spaces on metric mea- sure spaces. As our main result, we give a remarkably simple proof of the atomic decomposition.

New invariants and attracting domains for holomorphic maps in C2 tangent to the identity / Rong, Feng (Shanghai Jiao Tong University. Department of Mathematics)
We study holomorphic maps of C2 tangent to the identity at fixed point which have degenerate characteristic directions. With the help of some new invariants, we give suficient conditions for the existence of attracting domains in these degenerate characteristic directions.

On determinant functors and K-theory / Muro, Fernando (Universidad de Sevilla. Facultad de Matemáticas) ; Tonks, Andrew (University of Leicester. Department of Mathematics) ; Witte, Malte (Ruprecht-Karls-Universität Heidelberg. Mathematisches Institut)
We extend Deligne's notion of determinant functor to Waldhausen categories and (strongly) triangulated categories. We construct explicit universal determinant functors in each case, whose target is an algebraic model for the 1-type of the corresponding K-theory spectrum. [...]

Fraction-like ratings from preferential voting / Camps i Camprubí, Rosa (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mora Giné, Xavier (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Saumell i Ariñó, Laia (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
A method is given for resolving a matrix of preference scores into a well-specfied mixture of options. This is done in agreement with several desirable properties, including the continuity of the mixing proportions with respect to the preference scores and a condition of compatibility with the Condorcet-Smith majority principle. [...]

Elimination of resonances in codimension one foliations / Fernández Duque, Miguel (Universidad de Valladolid. Departamento de Algebra, Análisis Matemático, Geometría y Topología)
The problem of reduction of singularities for germs of codimension one foliations in dimension three has been solved by Cano in [3]. The author divides the proof in two steps. The first one consists in getting pre-simple points and the second one is the passage from pre-simple to simple points. [...]

Dense infinite Bh sequences / Cilleruelo, Javier (Universidad Autónoma de Madrid. Departamento de Matemáticas) ; Tesoro, Rafael (Universidad Autónoma de Madrid. Departamento de Matemáticas)
For h = 3 and h = 4 we prove the existence of infinite Bh sequences B with counting function B(x) = x√(h−1)2+1−(h−1)+o(1). This result extends a construction of I. Ruzsa for B2 sequences.

Blaschke products and Nevanlinna-Pick interpolation / Stray, Arne (University of Bergen. Department of Mathematics)
For a Nevanlinna{Pick problem with more than one solution, Rolf Nevanlinna proved that all extremal solutions are inner functions. If the interpolation points are contained in dinitely many cones terminating at the unit circle, it is shown that all extremal solutions are Blaschke products.

Logarithmic bump conditions for Calderón-Zygmund operators on spaces of homogeneous type / Anderson, Theresa C. (Brown University. Department of Mathematics) ; Cruz-Uribe, David (Trinity College (Hartford, Estats Units d'Amèrica). Department of Mathematics) ; Moen, Kabe (University of Alabama. Department of Mathematics)
We establish two-weight norm inequalities for singular integral operators defined on spaces of homogeneous type. We do so first when the weights satisfy a double bump condition and then when the weights satisfy separated logarithmic bump conditions. [...]

Conjugacy in Houghton's groups / Antolín, Yago (University of Neuchâtel. Mathematics Department) ; Burillo, José (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada IV) ; Martino, Armando (University of Southampton. School of Mathematics)
Let n ∈ N. Houghton’s group Hn is the group of permutations of {1, . . . , n} × N, that eventually act as a translation in each copy of N. We prove the solvability of the conjugacy problem and conjugator search problem for Hn, n ≥ 2.
