| Abstract: |
We study gradient flows of general functionals with linear growth with very weak assumptions. Classical results concerning characterisation of solutions require differentiability of the Lagrangian, as for the time-dependent minimal surface equation, or a special form of the Lagrangian as in the total variation flow. We propose to study this problem using duality techniques, give a general definition of solutions, and prove their existence and uniqueness. This approach also allows us to reduce the regularity and structure assumptions on the Lagrangian. |
