Computing the antipenumbra of an area light source
We define the antiumbra and the antipenumbra of a convex area light source shining through a sequence of convex areal holes in three dimensions. The antiumbra is the volume from w...

The Stability of Saturated Linear Dynamical Systems Is Undecidable
We prove that several global properties (global convergence, global asymptotic stability, mortality, and nilpotence) of particular classes of discrete time dynamical systems are un...
