DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NSCM/210/">O
 n the single field formulation in magnetostatics</a>\nby Giuseppe Tomasset
 ti (University Roma Tre) as part of Nečas Seminar on Continuum Mechanics\
 n\nLecture held in Room K3\,  Faculty of Mathematics and Physics\, Charles
  University\, Sokolovská 83  Prague 8..\n\nAbstract\nWe systematically di
 scuss the equivalence of two variational formulations of magnetostatics\, 
 in terms of the fields (H\,M) on the one hand and the single field formula
 tion using only B on the other hand. To demonstrate that this link is stab
 le also when the magnetic laws are coupled with other variational static m
 odels\, elasticity is included in the models as well. Interestingly\, desp
 ite the fact that the corresponding magnetoelastic energy densities in the
  material can be computed via Legendre-Fenchel transform in the magnetic s
 tate variables\, the two formulations are not linked by standard convex du
 ality on the level of the functionals. In addition\, convexity and coerciv
 ity of the given functional are neither required for the transformation no
 r always preserved by it.\n
