We continue here with previous investigations on the global behavior of general type nonlinear wave equations for a class of small, scale-invariant initial data. In particular, we show that the (4+1) ...

We consider the energy-critical semilinear focusing wave equation in dimension N = 3,4,5. An explicit solution W of this equation is known. By the work of C. Kenig and F. Merle, any solution of ...

Can one see through a scattering medium like ground glass? Conventionally, such a feat would be deemed impossible. As light travel through an opaque medium, the information contained in the light ...
