DOI: 10.1007/s00006-017-0805-z
Abstract: We consider the inhomogeneous div-curl system (i.e. to find a vector field with prescribed div and curl) in a bounded star-shaped domain in $$\mathbb {R}^3$$R3. An explicit general solution is given in terms of classical… read more here.

DOI: 10.1007/s00707-019-02602-9
Abstract: Noncentral force is an exemplary example of curl force and in general this is not an integrable system. The purpose of this note is twofold. First, we study a different reduction in the noncentral force… read more here.
