Title: Geometrical optics method for wave equations
Abstract: We show how to use the geometric optics construction to recover the light ray transforms of smooth compactly supported potentials from the hyperbolic DN-map on simple manifolds. If time permits, we give a quick overview of the Gaussian beam construction, which allows to achieve the same without assuming simplicity.

Title: Energy estimates of ray transforms
Abstract: The injectivity of ray transforms can be studied via energy estimates which are named after Pestov. I will give an overview on the energy estimates on Riemannian manifolds with boundary and show how one can use these estimates under some assumptions on the geometry to prove an injectivity result for ray transforms.
Time & Location: Tuesday, 27 January at 14:00, room MaD108, University of Jyväskylä
Speaker: Janne Nurminen (University of Jyväskylä & LUT)
Title: On nonlocal minimal surfaces
Abstract: I will discuss some aspects of nonlocal minimal surfaces, in particular nonlocal minimal graphs.
