Boundedness of rough integral operators on Triebel-Lizorkin spaces / Al-Qassem, H. M. ; Cheng, L. C. ; Pan, Y.
We prove the boundedness of several classes of rough integral operators on Triebel-Lizorkin spaces. Our results represent improvements as well as natural extensions of many previously known results.

ON D(-1)- Quadruples / Ciprian Bonciocat, Nicolae ; Cipu, Mihai ; Mignotte, Maurice
Quadruples (a; b; c; d) of positive integers a < b < c < d with the property that the product of any two of them is one more than a perfect square are studied. Improved lower and upper bounds for the entries b and c are established. [...]

Thompson's group is the orientation-preserving automorphism group of a cellular complex / Fossas, A. ; Nguyen, M.
We consider a planar surface ∑ of in nite type which has Thompson's group T as asymptotic mapping class group. We construct the asymptotic pants complex C of ∑ and prove that the group T acts transitively by automorphisms on it. [...]

Elliptic obstacle problems with measure data : potentials and low order regularity / Scheven, C.
We consider obstacle problems with measure data related to elliptic equations of p-Laplace type, and investigate the connections between low order regularity properties of the solutions and non-linear potentials of the data. [...]

Un théorème de point fixe sur les espaces Lp / Bourdon, M.
We establish a fixed point theorem for group actions on Lp-spaces, which generalizes a theorem of Zuk and of Ballmann-Swiatkowski to the case p ≠ 2.

Intermediaries in Bredon (co)homology and classifying spaces / Dembegioti, F. ; Petrosyan, N. ; Talelli, O.
For certain contractible G-CW-complexes and F a family of subgroups of G, we construct a spectral sequence converging to the F-Bredon cohomology of G with E1-terms given by the F-Bredon cohomology of the stabilizer subgroups. [...]

A degree problem for two algebraic numbers and their sum / Drungilas, P. ; Dubickas, A. ; Smyth, C.
For all but one positive integer triplet (a; b; c) with a < b < c and b < 6, we decide whether there are algebraic numbers α,β and γ of degrees a, b and y, respectively, such that α+β+γ = 0. [...]

On the power pseudovariety / Auinger, K.
The pseudovariety PCS which is generated by all power semigroups of finite completely simple semigroups is characterized in various ways. For example, the equalities PCS = Jm CS = BGm RB are established. [...]
