Abstract: | Let be a bounded Lipschitz domain and consider the Dirichlet energy functionalover the space of measure preserving mapsIn this paper we introduce a class of maps referred to as generalised twists and examine them in connection with the Euler–Lagrange equations associated with over . The main result here is that in even dimensions the latter equations admit infinitely many solutions, modulo isometries, amongst such maps. We investigate various qualitative properties of these solutions in view of a remarkably interesting
previously unknown explicit formula. |
