Abstract
AbstractThis paper is concerned with the Neumann problem for a class of doubly nonlinear equations for the 1-Laplacian, $$\begin{aligned} \frac{\partial v}{\partial t} - \Delta _1 u \ni 0 \hbox { in } (0, \infty ) \times \Omega , \quad v\in \gamma (u), \end{aligned}$$

. We prove that, under certain assumptions on the graph $$\gamma $$

, there is existence and uniqueness of solutions. Moreover, we proof that these solutions coincide with the ones of the Neumann problem for the total variational flow. We show that such assumptions are necessary.
