We study the $ L^2 $-gradient flow of functionals \mathscr F depending on eigenvalues Schrödinger potentials V for a wide class differential operators associated with closed, symmetric, and coercive bilinear forms, including case all Dirichlet forms (such as second order elliptic in Euclidean domains or Riemannian manifolds).We suppose that arises sum (-\theta) $-convex functional K proper doma...

Hybrid systems are dynamical systems exhibiting both continuous and discrete behavior. Having states that can evolve continuously or discretely, hybrid dynamical systems permit modeling and simulation of systems in a wide range of applications including robotics, automotive systems, power systems, biological systems, to just list a few. Key motivation for studying hybrid systems comes from the ...
