Fourier phase retrieval is the problem of recovering images from their Fourier intensity data. The standard Fourier phase retrieval (without a mask) is known to have non-trivial ambiguity, and standard phasing algorithms often stagnate at a local minimum, which produces wrong or inaccurate solutions. In this talk Fourier phase retrieval is studied with the introduction of a randomly fabricated mask.

The current talk is concerned with transition fronts of nonlocal dispersal evolution equations in heterogeneous media. As it is known, solutions of nonlocal dispersal evolution equations do not become smoother in space as time elapses. This lack of space regularity would cause a lot of difficulties in studying transition fronts in nonlocal dispersal evolution equations. In the current talk, I will first present some general criteria concerning space regularity of transition fronts in nonlocal dispersal evolution equations with a large class of nonlinearities.
