$On the boundedness on inhomogeneous Lipschitz spaces of fractional integrals, singular integrals and hypersingular integrals associated to non-doubling measures on metric spaces$

On the boundedness on inhomogeneous Lipschitz spaces of fractional integrals, singular integrals and hypersingular integrals associated to non-doubling measures on metric spaces / Gatto, Eduardo ; Centre de Recerca Matemàtica
In this paper we prove T1 type necessary and sufficient conditions for the boundedness on inhomogeneous Lipschitz spaces of fractional integrals and singular integrals defined on a measure metric space whose measure satisfies a n-dimensional growth. [...]

Elements of algebraic geometry and the positive theory of partially commutative groups / Casals-Ruiz, Montserrat ; Kazachkov, Ilya v. ; Centre de Recerca Matemàtica
The first main result of the paper is a criterion for a partially commutative group G to be a domain. It allows us to reduce the study of algebraic sets over G to the study of irreducible algebraic sets, and reduce the elementary theory of G (of a coordinate group over G) to the elementary theories of the direct factors of G (to the elementary theory of coordinate groups of irreducible algebraic sets).

Maltsiniotis's first conjecture for K1 / Muro, Fernando ; Centre de Recerca Matemàtica
We show that K1(E) of an exact category E agrees with K1(DE) of the associated triangulated derivator DE. More generally we show that K1(W) of a Waldhausen category W with cylinders and a saturated class of weak equivalences agrees with K1(DW) of the associated right pointed derivator DW.

Homotopy limits for 2-categories / Gambino, Nicola ; Centre de Recerca Matemàtica
We study homotopy limits for 2-categories using the theory of Quillen model categories. In order to do so, we establish the existence of projective and injective model structures on diagram 2-categories. [...]

Euclidean geometric invariant of framed knots in manifolds / Dubois, Jérôme ; Korepanov, Igor G. ; Martyushev, Evgeniy V. ; Centre de Recerca Matemàtica
We present an invariant of a three dimensional manifold with a framed knot in it based on the Reidemeister torsion of an acyclic complex of Euclidean geometric origin. To show its nontriviality, we calculate the invariant for some framed (un)knots in lens spaces. [...]

Subgroups of small index in Aut(Fn) and Kazhdan's property (T) / Bogopolski, O. ; Vikentiev, Ruslan ; Centre de Recerca Matemàtica
We give a series of interesting subgroups of finite index in Aut(Fn). One of them has index 42 in Aut(F3) and infinite abelianization. This implies that Aut(F3) does not have Kazhdan's property (T) (see [3] and [6] for another proofs). [...]

A class of stochastic games with infinitely many interacting agents related to Glauber dynamics on random graphs / Marinelli, Carlo ; De Santis, Emilio ; Centre de Recerca Matemàtica
We introduce and study a class of infinite-horizon nonzero-sum non-cooperative stochastic games with infinitely many interacting agents using ideas of statistical mechanics. First we show, in the general case of asymmetric interactions, the existence of a strategy that allows any player to eliminate losses after a finite random time. [...]

Brown representability follows from Rosicky / Neeman, Amnon ; Centre de Recerca Matemàtica
We prove that the dual of a well generated triangulated category satisfies Brown representability, as long as there is a combinatorial model. This settles the major open problem in [13]. We also prove that Brown representability holds for non-dualized well generated categories, but that only amounts to the fourth known proof of the fact. [...]
