DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Inverse/72/"
 >Stability of an inverse problem for a semi-linear wave equation</a>\nby T
 eemu Tyni (University of Toronto) as part of International Zoom Inverse Pr
 oblems Seminar\, UC Irvine\n\n\nAbstract\nStability of an inverse problem 
 deals with the question about whether small errors in the measurement lead
  only to small errors in the reconstruction. I will discuss the stability 
 and unique recovery of a potential function in a semi-linear wave equation
 . The inverse problem is formulated on a Lorentzian manifold. Using the no
 nlinearity of the wave equation\, we show that the potential function can 
 be recovered in a H\\"older stable way from the Dirichlet-to-Neumann map. 
 This talk is based on a joint work with Matti Lassas\, Tony Liimatainen an
 d Leyter Potenciano-Machado.\n
