 >Logarithmic stability in the inverse Steklov problem on warped products</
 a>\nby Niky Kamran (Univ. McGill) as part of CRM - Séminaire du CIRGET / 
 Géométrie et Topologie\n\nInteractive livestream: https://uqam.zoom.us/j
 /88383789249\nLecture held in PK-5115.\n\nAbstract\nWe study the amount of
  information contained in the Steklov spectrum of some compact manifolds w
 ith connected boundary equipped with a warped product metric. Examples of 
 such manifolds include deformed balls in R^d. We first show that the Stekl
 ov spectrum determines uniquely the warping function and also show that th
 e approximate knowledge (in a given technical sense) of the Steklov spectr
 um is enough to determine uniquely the warping function in a neighbourhood
  of the boundary. Second\, we provide logarithmic stability estimates on t
 he warping function from the Steklov spectrum. The key element of these st
 ability results relies on a formula that\, roughly speaking\, connects the
  inverse data (the Steklov spectrum) to the Laplace transform of the diffe
 rence of the two warping factors.\n
