28 p, 509.2 KB 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.

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.

9 p, 506.1 KB On the dynamics of the Euler equations on so(4) / Buzzi, Claudio (Universidade Estadual Paulista. Departamento de Matemática (Brazil)) ; Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Pazim, Rubens (Universidade Federal de Mato Grosso. Instituto de Ciências Naturais Humanas e Sociais (Brazil))
This paper deals with the Euler equations on the Lie Algebra so(4). These equations are given by a polynomial differential system in R6. We prove that this differential system has four 3-dimensional invariant manifolds and we give a complete description of its dynamics on these invariant manifolds. [...]

17 p, 333.3 KB On polynomial integrability of the Euler equations on so(4) / Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Yu, Jiang (Shanghai Jiaotong University. Department of Mathematics) ; Zhang, Xiang (Shanghai Jiaotong University. Department of Mathematics)
In this paper we prove that the Euler equations on the Lie algebra so(4) with a diagonal quadratic Hamiltonian either satisfy the Manakov condition, or have at most four functionally independent polynomial first integrals. [...]
