DESCRIPTION:Speakers: Clara Torres Latorre (ICMAT Madrid)\n\nPohozaev iden
 tities are conservation laws arising from the symmetries of certain operat
 ors. Their most classical example\, which gives name to them\, is an integ
 ration by parts identity that exploits the translation and dilation invari
 ances of the Laplacian\, with notable applications in nonexistence results
  for semilinear equations. In this work\, we use a novel spectral approach
  to prove a Pohozaev-type identity for the Spectral Fractional Laplacian\,
  an operator without translation and dilation invariances defined as the s
 pectral power of the Dirichlet Laplacian on a domain\, and we deduce nonex
 istence results for certain semilinear equations. This is a joint work wit
 h Itahisa Barrios-Cubas\, María del Mar González\, and Matteo Bonforte (
 Universidad Autónoma de Madrid). \n\nhttps://math-events.uni-bonn.de/eve
