Well-posedness for the continuity equation for vector fields with suitable modulus of continuity / Clop, Albert (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Jylhä, Heikki (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Orobitg i Huguet, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mateu Bennassar, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We prove well-posedness of linear scalar conservation laws using only assumptions on the growth and the modulus of continuity of the velocity field, but not on its divergence. As an application, we obtain uniqueness of solutions in the atomic Hardy space, H-1, for the scalar conservation law induced by a class of vector fields whose divergence is an unbounded BMO function.

Weighted Lp estimates of Kato square roots associated to degenerate elliptic operators / Yang, Dachun (Beijing Normal University. School of Mathematical Sciences) ; Zhang, Junqiang (Beijing Normal University. School of Mathematical Sciences)
Let w be a Muckenhoupt A2(Rn) weight and Lw := −w−1 div(A∇) the degenerate elliptic operator on the Euclidean space Rn, n ≥ 2. In this article, the authors establish some weighted Lp estimates of Kato square roots associated to the degenerate elliptic operators Lw. [...]

Potential maps, Hardy spaces, and tent spaces on special Lipschitz domains / Costabel, Martin ; McIntosh, Alan ; Taggart, Robert J.
Suppose that Ω is the open region in ℝn above a Lipschitz graph and let d denote the exterior derivative on ℝn. We construct a convolution operator T which preserves support in Ω is smoothing of order 1 on the homogeneous function spaces, and is a potential map in the sense that dT is the identity on spaces of exact forms with support in Ω. [...]

A Carleson type condition for interpolating sequences in the Hardy spaces of the ball of Cn / Amar, Eric (Université Bordeaux I. UFR Mathématique et Informatique)
In this work we prove that if S is a dual bounded sequence of points in the unit ball B of Cn for the Hardy space Hp(B), then S is Hs(B) interpolating with the linear extension property for any s ∈ [1, p[.

Continuity properties for the maximal operator associated with the commutator of the Bochner-Riesz operator / Liu, Zongguang ; Lu, Guozhen ; Lu, Shanzhen
In this paper, we obtain some strong and weak type continuity properties for the maximal operator associated with the commutator of the Bochner-Riesz operator on Hardy spaces, Hardy type spaces and weak Hardy type spaces.
